i think you're making the right choice to talk to your therapist. Maybe she/he can give you advice and coping skills on how to deal with these entities. After all, medicine can only do so much for us and we (unfortunately) can't rely on medicine 100%. We need skills to deal with crises etc.

Best wishes. I hope you're able to work through this! And I agree with Jennifer that you didn't do anything to deserve this. The only thing you deserve is to be happy.
