I am bi-polar and OCD. I have noticed a difference due to AAS. I have never gone to a shrink because I do not want that type of stuff in my medical records and honestly I am a bit arrogant and I have always believed it was something I needed to keep under wraps all by myself.
Long before my AAS use I read tons of books on managing depression and anxiety. I eventually overcame the OCD but depression and my bi-polar swings are always hidden the shadows and pop up every now and then. I have found ways to overcome depression and mental attacks through meditation, exercise, being with people who care for me, and just simply being aware. Not adimiting one has a problem is really the biggest obstacle to overcome.
I really don't have anything else to add to the above posts - IMO it is good stuff. If you feel comfortable see a shrink and also Oxycalm and the other things can help.
Hang in there and also know there are people out there that can help. It just takes time, patience, an open mind, and a solid plan, to overcome it.
