I am so sorry you are in so much pain.
I think it's a good thing that you felt you could call him and leave him a voicemail.
It's also a good thing that you have insight into the problems this may cause for you. It's best you and your T address these together.
Don't be afraid to let him know your feelings and all this brings up for you.
After all, you're just being an honest client. Therapists want honesty.
Your feelings, your reactions are valid. Please keep reaching out for support here. We will do our best to support you.
