I'm not sure if this can be attributed to BPD or if it's just me. Basically, whenever I begin dating someone or start a new romantic relationship, I always "lose myself" in the process. What I mean by this is that I begin to feel less passionate about my hobbies, non-romantic friendships, and work/college. In these times, all I want is to talk to or spend time with the person I'm involved with. Earlier this year, it got so bad with a different person that I became very depressed and felt like I had to drag myself through work and class and got nothing out of either of them, aside from irritation at having to show up to these commitments. This time around, I've done a little better so far. I'm still running (a major hobby of mine), even if it's only once a week. Of course, I know this will change if I begin to feel the relationship failing. I'm back in class this semester and feel ZERO motivation so far.
