I don't have the diagnosis on my record, but my psychiatrist told me he thinks I most likely have BPD. 

I've been fighting a lot with my boyfriend lately, mostly because I become paranoid that maybe he doesn't love me or because I suddenly decide that I hate everything about him and get snappy with him.

I don't want to hide behind a mental illness to justify my behaviour because I feel like that's a scummy thing to do, but at the same time, I honestly can't help it most of the time. Is there even a point in telling him? What's the benefit of it? It's not going to make my freakouts and fights any less hurtful.
