I think it's good to keep venting. I do find it hard to reply with some constructive feedback the last days, since I feel kinda lost most of the time myself.
Good part is, you are getting better!

Indeed it is a really hard fight and it hurts a lot to have to let go of someone you still love. I understand you have this feeling of, carrying the emotions for two. One of my earlier "temp" T's once said to me, you were/are carrying this relationship by yourself. No wonder you are breaking down. It sort of gave me some better feelings for someone to acknowledge that back then. Stay strong and continue to improve your own well-being! And ofcourse, it is okay to feel these emotions as well. There is nothing wrong with feeling like this sometimes, this is who we are and what we have been through.
