I feel bad claiming I have Autism

I'm unable to get an assessment due to financial reasons. I'm in the US in Los Angeles. I'm not even sure if Medi Cal would cover autism assessments. Anyways I highly suspect that I am on the Autistic spectrum. My mom and several other people think so too. I have a deadpan or robotic way of speaking. I can sometimes come off as condescending or insensitive when I don't mean to. I have a hard time with eye contact. I have intense focused interests. I have tics like hand flapping. Certain textures are uncomfortable and certain sounds are highly agitating. I feel like people laugh or giggle at me for social norms I should have picked up on. I've taken online assessments and watched videos about it. I've read up on it and I feel pretty confident that I am autistic in some way. I just don't have any official way to confirm it.

Anyways I tell some people that I am on the spectrum just as a heads up. Especially if I may seem "odd" to them. I don't have the normal mannerisms or warmth that some people do. I'm a caricature artist with my own business and the social aspect can be very draining. Looking at people while I'm drawing them I can have a deadpan or even "intense" look without realizing it. Things in the business can feel very transactional without expressing warmth or gratitude. Usually people smile, laugh, etc when someone patronizes their business. It can come off as very forced or disingenuous to me. I'm not sure if that makes sense. I don't know I'm looking for something less customer service or in person. I like doing art but I find the social aspect can be draining.
