I'm sorry you are going through this, if I was in your shoes I'd feel the same way. There is really nothing else for you too do but to try to accept that this is happening and face the loss, understanding that it is probably permanent but you also never know, you might end up crossing paths with this T again. Losing someone you're close to is one of the most painful experiences for a person, but try to accept that the pain is part of the great cost of love, it is inevitable for all people, it is like an emotional sacrifice because without risking great loss you cannot have great love. Time will completely heal this for you, and you can assist it by trying to do what you're inner voice tells you your therapist would want you to do. When the **** hits the fan the best thing to do is get out and be around people, and if you don't know where to go you can always volunteer your time somewhere.
