Am I the problem?

The other day my parents wanted me to let loose with myself in life but knowing I have a mental health problem and going through autism, i tried to talk to them about my mental issues and when I do they try to brush it off and say I need to breathe or exercise and I do those things (maybe its neglect)

I have 2 siblings and their out in the world and my dad doesnt care, but if its me its a problem and im the middle child

My sister is now a baby mama since she wanted a baby and my brother who is African American is in a ploy relationship with 2 hillbillies and im living my life with my dogs and I want to live my life in peace

It makes me feel like I wanna go no contact with anyone meaning family since they like to humiliate me, embarrassing me, make fun of me or make jokes about me

I wanna live life in peace and travel with no contact and if I ever have kids I wouldn't tell them anything or send pictures

I wanna make friends my own way but as an adult its hard and it can be easy to do things on your own since I've always done that and my parents werent there for me mentally or emotionally but only for my brother, and now were older hes disrespecting my mom and shows no respect and she cries alot and to my dad and hes cool with that and if I did that its a problem

I wanted to travel outside of America but my mom forbidden me and now im older almost 30 you now want me to go places which pisses me clean the fuck off and you have the nerve to tell me this now after I had to obey and listen and be loyal while your other kids run wild out in the streets

Or maybe I need therapy and move on with my life,

I dont know if I should follow my own steps or not?
