Gwolithing,
I don't know you, just what I have read in this thread... with that being said, I can tell you I am married to a man dx'd with BPD, he is a good loving man with a wonderful heart, who has many supportive friends, who at times need to take breaks from him, because of his black and white thinking and believing that everything is his fault or everything is someone elses fault.... seems there is no in between with him. Now I realize that there are numerous different types of BPD out there....

What I see is you asking for help and being very nervous about taking a step out there to ask for help and afraid of the rejection that may happen.. thus expecting no one to return your emails. By expecting this, then you can't be disappointed. What I see is you trying to reach out for support and what I see is others trying to reach out and support you.
I would try to see what they are trying to do... I know that my husband gets very angry at me at times when all I am trying to do is support him, and then he feels so guilty later... hang in there, be proud you are looking for someone to help you.
And so what if you prior T said you are difficult to deal with! T's should be able to deal with people who can be difficult at times, it is part of our defense to protect ourselves from more hurt... we didn't get this way by not being hurt somehow, somewhere in our lives.

You made a great step reaching out for a T that you can relate to and support you, if this step doesn't work out, it does not necessarily mean it is you. After all it is an email, they don't know you.. to make that determination yet.

Give it a chance. You have some great supportive friends based on what I have read from the responses.
