do you ever just feel alone?

i know im not the only one, but i always seem to feel lonely, and im always seeking validation from my friends, since my parents never validate me. in fact, my parents seem to invalidate me. my parents give me horrible mental breakdowns, i have at least one each month caused by my mum, and every time they try to make it seem like im overreacting. i honestly can't tell if i am overreacting and it's just my teen hormones, or if im in the right. sometimes they'll use my mental issues and insecurities to poke fun of, and then make it seem like im overreacting. and then there's the fact that it feels like none of my friends like me enough to consider me their closest friend. i have really bad jealousy, and i always feel left out or ignored in my gc. it feels like everyone in that gc is closer with each other than with me, if that makes sense, and i constantly feel alone, and have to read or watch tv instead of getting any actual human interaction. i also notice that i'll vent to one of my friends about it, they'll assure me that im worth so much to them or smth, and then they'll go back to whatever they were doing, and ignore me the rest of the day, unless we're at school or smth. it feels like i mostly interact with my friends at school, and we rarely get to talk about anything, really. anyway, i think i've yapped enough, i guess i just wanted to get that out of my system. i had no clue what to categorize this as lmao. i feel narcissistic for typing this now, and idk why.
