I think I might be having neurological issues, can someone help?

I’m a 17 year old, and for the last year I’ve been struggling. I started having nose bleeds every day, I eventually started having episodes that made me unable to walk to stand, my memory is no where near where it used to be, and I’ve become insomniac. Along with the insomnia, I’ve been having strange dream patterns and once again more issues with my memory. I’m starting to think I’m crazy, thinking that I remember something that doesn’t seem to actually be real. I don’t know what to do or think, and I just want answers. I am currently unable to get medical attention because of my mother canceling my insurance after disowning me. If anyone has any ideas or advice, please tell me.
