My anxiety gets me on a good day, but lately I have not been able to cope very well at all and am having daily panic attacks, and am just hurt!Back when I was 15 and emotionally stuffed anyway I met a guy who dated me, but refused to acknowledge it in public, and would always make me feel like I was crazy if I brought it up, and being as insecure as I was I just took love in anyway I could find it. (3 years on and off dating) He would also, with my friends who knew we were dating, flirt with them infront of me, including my sister. Now years later and having realised how my ex emotionally messed me up, I essentially have PTSD about it, I am happily married, but when I run into him I just get this tightening in my chest and the generally feeling of panic. I have done a really good job of not ever having to think about him or see him. Then my sister moved back to town (also married, though unhappily) she then started hangin out with him, and even though I had asked her not too, she just did not care and continued. Even though it is blatently obvious that he wants to be with her ( or at the very least hook up) now her marriage is on the rocks and her husband is moving in with my ex, I now have to hear his name on a regular basis and dread the thought that my ex will start showing up at faily functions and my sister says that I must just get over my problems and that he treats woman right. (His 4 ex fiances and I disagree)I think my biggest problem is that I used to feel like I was not good enough for him, because he always wanted someone else, and now I am not good enough for my sister, for her to believe me or choose me over him.Usually I have coping mechanism and moved passed her behaviour, but now she has moved back in with my parents and I see her almost daily and everytime it just triggers all my emotions again, really not sure what to do anymore.
