Hi Devastated
Welcome to the family.
Im sorry you've had to go through this. I can certainly relate to you missing your ex. I can also relate to not wanting to be on your own as its scary. What I will say is that being on my own has probably been one of the best things I have done. Its not such a scary place and has given me time to look at myself and come to understand why I do things. For all too long I believed I needed someone to make me happy and complete myself. Now I realise that only I can make me happy and I don't need to be completed because I am a whole person. I don't have to put up with bad behaviour because I am worth more than that.
It probably feels as if your world has ended and you struggle to do anything. It certainly did for me. I couldn't eat, couldn't sleep, my mind wouldn't shut up. I was at the lowest point in my life. It does get better though. Its not a quick thing. Slowly but surely you improve. Some days it may feel as if you are taking a step backwards and having to start all over again but you don't realise your new starting point is further on than you were in the beginning.
Keep posting and keep reading. It does help. There are lots of other things you can do to help you through this. Distraction is a major one. The less you think about your ex the more time you have to heal. Easier said than done I know.
It may be worth you reading the lessons and articles on the leaving board.
https://bpdfamily.com/message_board/index.php?board=8.0We mourn the loss of our relationship and as such need to grieve. This is perfectly normal. It may be worth your while having a read about the stages of grieving. We can sometimes get stuck in one of these stages which isn't good for us.
