Welcome
Working_on_it!
I am so very glad that you have found us and joined us here on Coping and Healing.

We are a big online family dedicated to supporting on another and learning as we heal from the effects of having a pwBPD in our lives. Have you taken a look at the right hand side of the board yet? ------>> Click on any of the steps and they will open up into a larger window. Also there is a whole lot available to read. Is there anything in particular that I can direct you too?
Some of what you shared reminded me of a book I read by Donald Miller,
Scary Close, which a friend recommended to me. I looked to see if we had a review in our book listings but did not see it. The book does not deal with BPD, but the principles and heartfelt sharing within the pages clearly apply to how I felt (and the author) due to great fear and inability to form intimate relationship. For me it was because of the effects of BPD on my own life. My mom was a high functioning uBPD. Oh! How much that has been the forming base upon which ALL of my relationships have been based.
I am glad that you are beginning to make sense of this all in your life. None of us can go back and change the past, but we often do need to look back at our past in order to learn, understand, and dissect the truth and falsehoods which we have believed. I also wish you had some of this information sooner, but it is important to know that you have this treasure in your hands now, and it is and will influence your present and future. It is a gift you hold now. So glad you've found a good T! Mine has been worth his weight in gold to me, accompanying me on this journey to healing and recovery.
Looking forward to hearing more from you!
