Living with opposites (s**cide mention)

I have never had a typical toxic family, where they get mad and throw me out or anything like that. It's always been more of mental obstacle courses dealing with my family. I am a very expressive person in terms of my appearance/decorations. I am the complete opposite of my older sister, who is very loud, aggressively bossy towards me, and a ranch girl. We grew up on a ranch, but I've never been into it. I especially hate doing the chores that now I technically don't even have to be doing since the animals belong to my sister now, but I do them anyway so my family doesn'r call me lazy(even though they already do). My parents and sister are Catholic Republican conservatives. I am not, and adding onto that, I am an identity-struggling pansexual(though i wouldn't tell them in my life. Tried telling my mom that I liked girls once, and her response was to repeat "no you're not" until i couldn't handle crying in front of her anymore).

Yeah, I can say that I love my family. Even after having the worst few years of high school you could imagine, I still didn't k*ll myself (a shocker even to me !) And I eventually graduated. Now, after a few more months, I will be able to move out and escape my pre-diabetic mother who doesn't shower and sleeps all day, my dad who will not stop turning on his damn conservative radio talk show or wearing his trump hat in public next to me, and my sister who will not stop looking down on me and treating me like i'm a five year old child.

Edit: this really bothers me, too. I never did as well in school as my sister did. I never had plans to go to college, but my sister did and she is now a vet. I feel like because I never could share what I was going through to my family, my parents never considered that I went through some fucked up stuff, as my sister did in high school. When I am badly hurt and feel like shit, I typically hide it. So now, when I try to get my parents to understand what I went through, they say it's not as bad as what my sister went through. What the fuck.
Just yesterday I worked up the courage to tell my mom that if it weren't for anime and k-pop distracting me in freshman year, "I might not be here" (is what i said. What i wanted to say: "i would've killed myself"). She didn't get it at first, I repeated what I said, then changed the subject.

Advice: take it a day at a time. Keep reading manga, no matter what genre it is, because that will keep your mind preoccupied so you can survive. Maybe get interested in something else as well(I recommend k-pop). When you leave/move out, do at least one thing that your parents wouldn't let you do before for the grand finale, whether that's skip a sunday from church, get a tattoo, or have gay sex for the first time, have fucking fun with the sweet freedom you will have.
