Real Life Problems

I'm just gonna let this out because I feel like if I don't write it down I'm going to explode, and yes this is in an alt acct, because I'm a #pussy and when I vent I feel like that sad bart meme
Anyways
I can't reach out to my family, and I don't mean literally, it's just that talking to them makes me me feel like I want to choke on glass, expode and kill myself in the process
For context, I'm in another country very very far from my family because I'm studying, my family has a group chat where they all talk constantly about anything, but I've never really texted there, because I feel like if I don't have anything important to say, I just don't want to talk
I've always had a rocky relationships with my parents(specially my mom) and with my sisters too, I've never been affectionate with any of them, and plus, we're asian, so yk...
I stuggle pretty much everyday bc I have depression, and it doesn't help that the few times I've talked to both my parents and sisters, we just end up fighting
This time, my mom was asking me if everything was alright, I answered her 'yes', and she got mad out of nowhere, she started telling me how I don't care about the family, how I never call nor text, how no one in society is going to like me because of the way I am, and that I'm going to end up alone, that when I have my own family, they're going to do the same to me, and she ALWAYS says things like that, that I'm inconsiderate, she compares me to her friend's kids, and how they always call each other every now and then, but I never do anything
Part of it it's true, I don't really reach out to them, and this is gonna sound pretty shitty of me, but I don't miss them
Every time I talk with them, they either think they're always right and I'm in the wrong, so we fight, and dismiss my feelings or belittle them, or they don't even want to hear what I'm saying, and when I say that talking to them makes me want to literally kms, I mean it, I always end up feeling like shit
I go back to my gallery and see some old videos where they took before I was born(I'm the little sister of 3 daughters) and I always wonder if all of them would just be better off without me, they all seemed so happy
Even in the group chat they send photos and videos together, I can't help but wish I wasn't even part of that group chat, just dead honestly, it would make their life easier, since my mother constantly says how always make her suffer because she fights with me all the time
I appreciate everything they've done for me, and I will always be grateful for them, but I can't help distancing myself from them, when I just feel shit everytime I do talk to them, it's a full on mental toll that I take week to recover from
I'm just so tired of everything, the guilt is eating me alive, and every night before going to sleep I wish I didn't wake up the next day
Sprry for the long rant

Alright, so i have 2 older siblings and a younger one. My eldest sister is the problem. Shes had a habit of stealing money and shit arount the house, and this is an open secret among our family. My mom told us that when we were kids a 500 note was missing from her bag and she asked my second sibling about it ( this was at night and every one else was asleep, we siblings all share a room btw) second sibling said they hadnt seen it and mother left the room, so they lay down to sleep....around 10 mins later they see eldest sis sit up and pull out the note from the gap above her in the bunk bed, open the note, stare at it, and then she puts it back and goes to sleep.
So anyways the other day second sibling asked me to buy them tickets to a movie and i brought back her money with two 100 notes and told her i couldn't keep the cash with me cuz all my cash has been going missing from my wallet the past year or so. The next night i remember clearly leaving some cash in my wallet (around 5 diff types of notes added upto almost 50 in total, btw i had cash on me that night cuz the cinema only accepts cash fsr, there's some shady shit going on there) next morning i go to work and all my cash is GONE (╬￣皿￣). I was so pissed i ranted in the fam grp chat about it losing my cash in our shared room, and asked for it to be returned if found. Not even a minute later second sibling calls me and tells me that one of the 100 notes i gave them was missing from their pouch, how shocking!! I actually didnt think she would steal money from second sibling cuz thats the sibling shes on best terms with.
Now you may be wondering how i know shes been stealing my shit. So my mom bought me pair of very expensive good quality sunglasses, which i let my family borrow if they're going on a trip or if i dont use it. One day i left it on the table while running some errands (shopping etc...) and when i went to step out again, it was gone. The only ones in the house were me, my dad, and my eldest sis. My dad was deeply sleeping on the sofa (i had tried to wake him for breakfast but he was put cold) so i knew it wasnt him, and eldest sis had stepped out 5 secs ago, i called out the door to her and asked if she'd seen them but she said hadnt.
Fast forward 3 days, im still looking for them, checked the whole house, asked my family, and the only conclusion was that she took it, so when she was home and i had the room to myself i locked the door and went snooping through her bag. What i found was an unopened pregnancy test, cigs and voila, my beloved sunglasses sitting at the bottom of her bag. Glasses that she denied having seen when i has messaged her the day before. I took a photo of it sitting there in her bag and decided to confront her later that night infront of the rest of my siblings....
Unfortunately, that night i saw the glasses sitting in plain sight on her shelf and she told me that my baby cousin must have put it there, thay pos
Anyways, i told my mom and as always she told me i should leave my things around her, which is impossible to do in a 2 bedroom apartment with 6 people living in it.
Thanks for listening to my rant guys ヾ(╹◡╹)ﾉ~
