Major TW

I feel like if I was to completely cut off all contact with my entire family I feel like men would see this a red flag when I start dating. I tried foing this before and people where so unforgiving like I deserved the abuse or that I was a awful person for wanting to not be apart of my family. What I go through with my family mainly my toxic sister has me really considering SI. like I really can't take it. Like she's 23f and im 24f and we live together as roommates I wish I could move out. I make enough to live on my own but our lease is not up untill June of NEXT year. I've asked my step mom for help and even she doesn't want to take my sister in if i was to move out. This just sucks honestly. I'm tired of my sister mocking me for working 2 jobs, making me for battling with severe depression, mocking me for having a shitty dating life when she has never even dated herself. Also she likes to make fun of me for buying myself new outfits and make up. Now she doesn't wear make which is fine and she's small enough to just walk into target and buy herself something pretty if she wanted to. She has a full time job and goes to school to so I'm definitely proud of her I just wish she wouldn't make fun of me for not having the balls to start school. All the horrible shit she says to me really makes me want to go through with SI as I just don't see a way out of my situation. All my family is toxic, my birth mom, my birth father, step mom, grandparents, uncles and aunties. If I cut everybody off it would literally just be me and my cat.

My life is awful

EDIT- Thank you guys for all your kind words and advice. I just spoke to the leasing office and she said I can totally move out the unit and get my own!!! I just have to put down deposit and resubmit documents
