Thank you for writing. Your letter shows me that your therapy has helped you become very self-aware. It may be time to consider a change in or addition to your treatment plan.
The answer to your question isn’t simple. Yes, you have issues to work on. But the fact is that so does everyone else. The fact that you are desirous of a relationship is an indication that therapy has been successful in helping you get ready to confront the avoidance behaviors that are getting in your way.
I suggest that you and your therapist consider referring you to group therapy now. As valuable as your individual therapy has been, you are talking about your behaviors rather than dealing with them directly. A group requires you to interact with others in the group in vivo. You will be dealing with your behaviors directly and immediately, not just talking about them. In group, you can learn more about how others see you and can safely practice handling things in a new way. You will learn from each other and support each other in your healing.
Do talk to your therapist about either transferring you to group therapy or adding group to your current treatment plan.
I wish you well.
