Carlos,
I've experienced the EXACT same thing you're describing while on sus. and deca. It caused huge problems between my wife and I and I described a lot of this in a previous thread about xanex. I described it more as anxiety rather than paranoia but that condition definitely came to mind. I made an appointment with my dr. and was prescribed ativan which apparently is more addictive than xanex so I really haven't touched the stuff much. However, I haven't experienced anything near the same level of anxiety during my current cycle of test prop and deca. I figured it was more about stable blood levels and how I was taking the sus. verses the prop but now that you mention your condition, its got me wondering again.
Now, for the record, I've always been kind of a suspecting and cynical person and thought the steroids may have just amplified those personality traits. And I also have rather strong trust issues with regard to women, maybe even myself as well. But there is no doubt that my cycle that included sus was much, much worse than the cycle including prop. Like night and day. Not sure if this adds anything to the discussion for you but I hope so. Best of luck and I hope you find relief. I know all too well how badly this sucks.
