I have never felt an urge to self-harm in any overt way before. During an intense episode in a relationship, I might headbang with my hand, or punch a wall, or a bed, but I usually have enough restraint not to do lasting damage. 

Ever since my diagnosis however, I am getting frequent, repetitive intrusive thoughts about cutting myself or smashing something dangerous over my head. It's gotten to a point where I'm blasting music on my headphones and laying in bed for hours just to avoid thinking about it. 

Did this happen to anyone else? Do symptoms of BPD frequently get worse after you get diagnosed? Wondering what the hell is happening here, I thought I was supposed to get better from therapy and effort.
