cillian murphy’s big toenail's Things

i’m asking here cuz i seriously don’t know who to go to. short backstory, i have a group of friends that i’ve been with way baaaack and i ranted to them (idek if my grammar’s right right now cuz my mind’s just like all over the place”, i was ranting about the amount of schoolworks (i messaged them in a group chat btw) i had since i was from a diff. school, then one of my friend comes at me and lowkey invalidated the stress i’m feeling right now. like he’s comparing their work to my work and saying things like he’s got it harder. and then i sort of lost it when he said that, i sarcastically told him “wow, you must’ve been suffering from all that. you definitely have it waaaay harder than me.” and he’s like “ikr”??? i just left him on read and he messaged me directly saying that it was a joke and said those things to make me “motivated that he’s having a harder time than me and that i shouldn’t rant about nonsensical things.” and he didn’t say sorry, so now i’m overthinking if this is my fault or his?? i’m overthinking rn cuz literally no one in the group chat’s acknowledging the fact that i’m literally hurt and feel like my feelings are invalid??? am i being needy or should i just let them be??? ┗( T﹏T )┛
