Hello, Amanda. What you describe is quite the enigma. You and your friend have been together for a long time. Yet, she has a boyfriend? Not a friend who happens to be male, but a boyfriend?

You say you feel absolutely nothing, but are angry and want the passionate relationship you and she used to have. That is not apathy. To add to the enigma, you show your mood is happy?

You list some very serious mental health concerns. Are you receiving treatment for them? Is your friend dealing with illnesses too? If so, is she getting help?

My thought is that the relationship is not going to get better unless you and she take better care of yourselves. You need to deal with the illnesses.

Good luck.
