Controlling the Green Eyed Monster

Sometimes I think I’m destined to spend the rest of my adult life alone. Even though I’m in, what I believe to be, a happy relationship, I feel that at any given time I’m going to say or do something that will ruin everything and leave me alone once more. The worst part is that I feel it’s what I deserve, and it doesn’t stop at my private life, I don’t think I’m worthy of sporting, academic, or professional successes either. This, I believe, is the root cause of my sabotaging anything that vaguely resembles the beginnings of something good in my life.
