Not sure if I would say he could have borderline personality disorder, but I always headcanon Foggy as being as fucked up if not more fucked up than Matt, and we just haven't seen it yet. Based on what we've seen and what's said about him (Marci's "afraid of commitment" comment, his drinking, his insults to her and his offer to drink with Karen, his singing Gilbert and Sullivan late in the office) I definitely think that there's room for a "Something is a bit off about Foggy" headcanon, for sure.
In fact, I'm pretty much already writing one that's a WIP about him and his birth mom, or I'd take this one on. I hope someone picks this one up and runs with it though!
