Do I have SIBO?

Hi all, 

I have been suffering from the following for around 5 months: 

- Insatiable hunger

- Stomach pain, bloating

- Fatigue

- Brain fog & lack of concentration (usually because of the stomach pain and hunger pangs) 

I have tried numerous medications and currently take a plethora of supplements (Oregano Oil, Probiotics, Alimed amongst others). Nothing seems to make any difference, and in fact my symptoms are becoming worse.

Moreover, at my worst points, I consider suicide. I am completely unable to concentrate on anything that isn't the pain or the incapacitating hunger. 

I could go on, but rather than doing this I would like to know if what I have sounds like SIBO. Any help or guidance is appreciated.
