I am back on my medication but want him so badly. He was my rock. He wants a clean break. I’ve asked him to support me until I’m better.
Ok. I understand that you are hurting at the moment but this paragraph really jumped out at me.
You were together for less than a year and he had no idea about your anxiety and depression. There isn't really a problem with that if you're managing it but you also say you came off the medication. Why is that if you still needed it?
I wondering the relationship made you feel 'better' and so you decided that you no longer needed it because you had him?
Unfortunately, that is very intense and a huge pressure for someone you are still getting to know.
You say you became insecure and needy and pushed him away. I've dealt with the insecurity and neediness caused by unmanaged anxiety and depression both personally and from another person and it is horrendous for both parties.
He is actually doing the right thing for himself and for you in not refriending you on Facebook. You need to move on and he needs to protect himself and his own mental health. He is right to want a clean break.
It's a huge responsibility and incredibly draining to support someone else through anxiety and depression. He might not want to be someone else's 'rock' after such a short relationship and he is under no obligation to support an ex girlfriend until she is 'better'. That could become a lifelong commitment really couldn't it?
I'm sure you'll have plenty of people who tell you you've dodged a bullet, he's a dick and that if he loved you he would but life is not like that. He is a person in his own right who deserves to be in a relationship that he finds fulfilling and in which he is happy.
I don't think telling you he still has feelings is him dangling a carrot. I think he is trying to be kind. He's not telling you you are unloveable but that you're someone he can no longer be in a relationship with. He is being quite clear about that and that there are no mixed messages. That is why he is not adding you back on Fb and why he isn't offering to support you.
Go back to the GP and back on your meds. They are the reason you felt better and were able to function in a relationship, not him.
