I have food issues. I used to binge and purge (but then again, I also have an eating disorder), but I don't so much purge anymore. My T says the purging these days are an act of self-harm, though I really don't know. I am doing pretty well with food lately, am watching what I eat, and have lost 10 lbs so far. But I know that when I am in distress the first coping mechanism I always reach for is food. Always. There are others, but they come after food. I can't tell you if this is specifically a BPD thing, but the reasons why food is an issue for me stem from BPD so...yeah. I guess you could say it is.
