I am a really worried about my health

I have been complaining about my general health for about 5 years. It all started when i was 23. I caught what i felt at the time was a cold but after a month I started getting help

I have needed to go to the urinate every 30 minutes, give or take, for the whole 5 years.

I am also dizzy most of the time and it's worse when i am not moving. I am confused and exhausted all the time and worse in the early mornings and at night.

I feel hungry all the time but I am also severly constipated. I now suffer from really bad self esteem and my friends and doctors think I am crazy.

I have received a variety of treatments from the doctor but none have really stopped any of the symptoms very effectively. ANti-depressants, Anxiety pills, various stomach treatments/colonic irrigation, Psychatriasts that I still see.

I get ringing in my ears all the time, My doctor said it was tinnitus but I live in the middle of nowhere, and don't have any noisy hobbies. I work at a computer.

I feel at the end of it.
