I withdrew myself from most social things after I had been battling the urge to for a while this fall. It was therapeutic and needed to an extent, but I also isolated myself a bit too much. At this time, I was still working, going to school, and doing extra curricular stuff. I think that it's good to take breaks to reflect, revamp, and heal old habits, but it sounds like you're isolating too much to me.

I think that BPD people need to get used to being alone. We are misunderstood folks and can be too needy on others at times. It's important that you do things even if there isn't someone to do them with you.
