It sucks to live with BPD as well as OCD, but I'm thankful, let me explain why; I have extreme anxieties and a lot of compulsions, and periodically one is more prominent than the other, however, my OCD always jumps to the worst case scenario, and because of this I'm afraid of splitting and losing my boyfriend who totally understands it. I feel like having OCD helps me have a bit more control over my BPD which used to be almost unmanageable before I was diagnosed. The downside is that the splitting, irritability, impulsiveness, etc. is managed fine, but having both means double the intrusive thoughts, and a lot of repressed emotions out of fear. It bubbles up inside of me and all I can do is sit down in a dissociative state as to not hurt the people I love or myself. It's not as healthy, but I'm a massive overthinker, and I've learnt to adapt to exposure therapy. 

I still have the pettiness and irritability, as well as psychotic traits that are hard to deal with most of the time, but I think if I didn't have OCD, it'd all be so much worse. They cancel each other out, but with that means an extra load on my shoulders and figuring out how to sort through it without repressing. I keep myself going because I'm scared of going downhill, and I'm scared of losing control. I am very stern with myself not to be reckless. 

It sucks, but before I learnt about my disorders, I was very unstable and my boyfriend and I didn't know what was wrong. It was constant arguing and having a go at each other, but now we understand each other. 

It's funny having polar opposite disorders... one is like, recklessness and impulsiveness and the other is anxiety and control.
