Welcome Saly!
I know how hard it can be with an angry or mean alter. It sure is difficult to know what to do in this time of being freshly dxd.
It will take time to open up channels of communication if that is something you and your therapist think is safe for you to do.
Glad to see you here. Ask away with questions as there are some amazing ppl in here who have lived with this dx for years and then others like you and me who are relatively new to this all. (for me dx was about a year ago I think....can't remember well)
