I'm scared to go to doctors b/c i went to them multiple times with the same issues in past two years. most issues were left untreated and without testing, still are causing problems/getting worse. i feel doctors think i'm paranoid. what should i do?

I doubt that the word is scared. You may want to see a therapist rather than a doctor; and it does not mean you are crazy. Doctors are more inclined to treat what they find to be abnormal obviously and physically; whereas therapist are better at discernment of things that may cause symptoms but are actually not because of physical abnormalities.
