I have posted on this subreddit about a break up I had a few months ago. My ex and I had a falling out, and are no longer in contact, and I'm a little out of sorts. He said he cheated on me in the beginning of our 2 1/2 year relationship, so I feel extremely betrayed and hurt. I have always had abandonment issues and this is the tipping point. He said he would be there for me, he said he loved me...it was all a lie. I'm just looking for some advice on how to live on my own and be by myself when I go crazy. Basically I have extremely catostrophic thoughts and they make me go insane. I just need some help.
