I think I have ASD and am Bipolar

As the title suggests, I believe I have both of these disorders. This post is kind of a blend of all my problems. Advice and motivational words welcome.

I am 17, and I've tried talking to my mom once, she said no to screening. It's a very uncomfortable talk (Asian parents), and they rarely change their minds for anyone. I really want to get screened because it's very important to me to know whether I have it or not.

I have taken online tests, that indicate a high likelihood (apparently thats as strong of a statement they'll make), which just tells me what I already know.

I don't know to handle relationships - I'm talking to this girl I really like, she also has ASD but she's so good at relationships - like she's super natural about them, and I can't help but want to talk to her more, but she's more 'normal' than I am, and doesn't match my desires.

Everything is just falling apart. I don't know how to act. No friends at school. Miserable and alone. f*kkkkk
