I am sorry to hear that you are in pain. I had msn breakup with me while I was in a depressive state. It hurts a lot. Sometimes it hurt to breathe. I would talk to your doctor and tell him/her what you are experiencing. Maybe he can help.
If not talk to a counselor. They can help you cope and give you the tools to get over this hump.
Major hugs to you. I am so sorry you are hurting.
