I am in a happy and generally successful relationship. Recently there have been bumps. I am having a harder time controlling my thoughts and anxiety and often time things pile on and I have these anxiety attacks that I can’t control at all and I fear I’m hurting him. He is so good to me and I can’t help but feel like he should be better with someone else who won’t cause him as much stress. We are engaged to be married and I’m afraid he’s gonna have enough of me one day and leave because he can’t physically take me anymore…
