Jazzy - from your post it sounds like therapy is the place you should be. You have picked up on something you need to work on in your relationships with other people (Misunderstandings and withdrawing; running away from confrontation). Therapy is like a play-pen environment; we are safe and are guided. This is place you can address your issues in a safe environment and take your learnings from here into life.

I don't know your relationship with your T, but if it's meant to be, you'll be able to address this issue with her, and she'll be able to iron out any fears.
I tend to blame myself for any misunderstandings too, I get paranoid that relationships are always on the rocks - I do understand. I am scared to get involved in ANY type of relationship for fear that I may hurt someone, or could end up feeling abandoned by the other person.

But when these issues arise between you and your T, it provides a fantastic opportunity to work through it with your T. Take what you learn through working through this with your T, and apply it to your relationships in your life.

If you still have things to discuss with your T, don't think twice about booking that next appointment
