The personality diagnosis symptoms do overlap. In addition to the overlapping, we are complex individuals and a snapshot of 'how' we are is not static. The label isn't important and some therapists don't offer a diagnosis.

What's important is that you want your life to feel better. It's a great start to be open about yourself. The willingness to look inside can be hard to attain. I hope you'll consider working with a therapist to explore the things you talk about in your post, to find out more what they are about and where the feelings originate that drive the behavior.
