AITA i'm sick of living with two people in a two bedroom apartment

For some context.

my parents got divorced when i was 3 years old, and ever since then i have lived with my mom, she works alot to feed me and her, and when i was a kid i used to be home alone all day, i got used to it, and i love the freedom that being alone gives, so my whole life i have been the whole week home alone but now she works from home and she recently she got married to a dude and he is a good guy and i like him, but he recently quit his job and now buys and sells cars and he is all day HOME and i'm sooooo sick of having two people i'm the apartment it's soo overcrowded and i just can't take it anymore, my dad lives alone and he works in a office but i don't know if i should move into his apartment he is very introverted like me and i don't know if he would like me living in his apartment.

I think i should just "man up" and get used to it, but it's very mentaly exausting living with soo many people in apartment ¿AITA for wanting to leave?.
