Hi, I suspect I might have bipolar disorder l.

I have been suicidal on different occasions at one point a went to a gp and explained this and that I was concerned about my long term mental health. They told me to look at online resources and books so I did. I bought a book on cognitive behaviour therapy and it has helped me deal with depression, however since doing so I have been very suicidal at least once, following manic sexual behaviour. At times when I lose control of my emotions and browse escorting sites and look at cam girls for hours I feel hopeless and tremendously ashamed. I thought I was a sex addict however the majority of the time I'm not preoccupied with sex.

I'm quite concerned as after these periods of intense sexual novelty seeking behaviours I usually feel very depressed and again near suicidal. 

Alot of my life has been defined by extreme highs and lows.

I really don't know what to do here, and I am sure that if I go to a gp I may be misdiagnosed or not even diagnosed considering how they handled me explaining my suicide attempts.

Can anyone help me?

What should I do? Thanks.
