Schizophrenia/autism...

I have schizophrenia and autism, im on medication for my schizophrenia, I've been with my boyfriend for over 2 years and i feel like im a burden him having to make sure i don't do stupid things making sure i don't hurt myself making sure i eat etc. But he also has to help me with day to day things due to my autism. I feel like such a burden and I feel he deserves someone so much better someone he can go out in public with who wont start crying because of crowds someone "normal" i feel he deserves a better woman😩😩 Advice please?
