Feeling Like a Burden: Living with Autism and High Support Needs

I tired of being and feeling like a burden to my family.. I have medihigh support needs, and I can't live alone or work I have frequent meltdowns, I can't keep myself safe. me and my dad had to move in with my other adult siblings(found not by blood) because hes physically disabled and couldn't take care of me I just recently found out that's the reason whe a family friend was yelling at me for "always doing this" whe I was having a meltdown..I was even a burden to my own father and now I just am to my siblings because I cant take care of myself like a "normal" adult.. I talk lot about being proud of being Autistic and I mean it I'd never change it but it is so goddamn hard sometimes..
