I think this is definitely something you should bring up in therapy, if for no other reason than that she's aware of how you are feeling and the pain you are going through. Maybe she'll have some suggestions on to get through to your mom and your boyfriend.

Definitely continue to post here. PC is a wealth of support.

Maybe you could ask your boyfriend to come to a session with you (after you talk to you therapist about all of this). Maybe your T can help open his eyes to the roll he needs to play in your recovery. He simply might not know what to do.
