How do you get diagnosed as an adult?

I'm a 24 year old female living in a rural area with my closest city being Baton Rouge(Louisiana)and so far the doctors...don't seems all that great. Most have bad reviews while others won't even diagnose adults. Is there anyone here from the BR area that knows of any good doctors? Or if getting a diagnosis through a doctor online is an option how would I do this?

I'm really struggling with finding the help I need and I have no idea who I should turn to so I would really appreciate any recommendations.
