Hi Ambush,

Welcome to the community. I'm so glad that you decided to post. I'm sorry that things have been so tough. I can understand feeling nervous and like things are getting worse for you. I had several physical symptoms during my relationship as well.
You are definitely not alone. And there is hope for things to get better. You'll find many members here who understand what you are going through.
I think counseling is a great idea. We all need support, and an objective and caring perspective can help a lot. Will you also be able to get counseling just for yourself, Ambush? I highly recommend it if you can.
Have you explored alternatives to picking your skin? Vigorous exercise might help. And/or meditative activities/hobbies. When I get very nervous, I try to focus on my breathing. Sometimes making the exhalation just a bit longer than the inhalation can help, but just focusing on the breath can be enough to slow things down, mentally and physically.
Keep posting. We're here to support you.
