Speaking for myself only ... yes. USMB is / was a form of therapy.
Shortly before I joined this board, I had left another. One in which I became emotionally involved, taking EVERYTHING personally and losing track of what was important in my life. In a nutshell ... I suffered from internet addiction.
I joined this place looking for another online 'home'. After a few posts, I left. When my life started to get back in order, I started posting here again. Teaching myself that I can be online meeting people and communicating, and still have control over my real life.
Ahhhhhh ... life is good.
