I'm just starting to realize/wonder if my ED and BPD are at all related to or are feeding off of each other. I was diagnosed with anorexia nervosa first, and then diagnosed BPD a few months later. I didn't think the two could be related in any way until recently, and now I'm pretty sure there's some kind of connection there. For me, my ED is mostly related to pleasing others, as backwards as that sounds; I become convinced that gaining weight will make people love me less, and I have a serious fear of being alone or friendships falling out, so I either lose weight or maintain a certain number that I think people will "love me most" at. I've been eating more recently because I was threatened with residential &amp; I honestly cannot see that being a positive thing for me (heard a lot about how ED patients actually spend their time in residential observing other patients &amp; trying to get more tips and tricks for losing weight, and they usually relapse shortly after being released because of the intense guilt over weight gain. idk maybe that's just me talking myself out of much needed help... I kinda like hurting myself &amp; ruining my own life like that lol), and was also threatened to be kicked out of my boyfriend's house because he cannot deal with the intensity of the relapse &amp; my intense mood episodes from my BPD. The episodes get worse as I lose more weight, especially if I see that I've gained "too much"; I literally beat myself up because I am convinced that everyone will just be staring at my "stomach pooch" or "chicken wing arms" and think I'm a failure and really gross, and that they won't want to be friends with me, let alone look me in the eyes or respect me. 

I have no idea if this means that my BPD is related to my ED at all, but I really feel like they're pretty closely related. The fact that it's mostly about pleasing others out of fear of them leaving me is what really makes me think they are. IDK. Ugh. Looking for some support &amp; also wondering if anyone else has both diagnoses and suspects they exacerbate each other's symptoms, or if it's only one or the other that's the main problem.
