Should I get screened for autism?

I need to know what to start crossing off the list so I can get the help I need. I I can’t afford testing, but if my symptoms are cause enough, I will come up with the money to pay for it. So basically. I have frequent issues like not being able to understand facial expressions (I can understand tone of voice but not if it’s face to face). I get yelled at a lot for interrupting people. I have tics where I make a pop sound and jerk my head. I only know what emotion to expressed based off what I’ve learned. I also internalize everything. If I see a show or meet new ppl I begin to act like them. Like I watch charmed and then I think I’m a witch for a period of time. I don’t understand reality vs what I’ve made up. I have severe depression and anxiety, I isolate myself as much as I can, to the point that I leave my apartment to sit in my car and close my eyes. I cant wear makeup bc I fixate on how my face feels and my tics start to increase. Also the second I start to feel food or gum in my mouth, I have to spit it out. I can’t look away from food or drinks otherwise I think there’s bugs in it. If I’m told something and I don’t understand it, I will not be able to comprehend at all until the way it’s said is completely changed
