Does anyone else experience urges to self harm when they aren't necessarily sad or in distress at that specific time? 

I find myself constantly talking myself down in my head from urges to cut myself or bang things against my head. I don't know why. I feel relief when I do it and haven't found a way to quiet the thoughts. I don't know if it's also a response to stress or anxiety, and I would really like to try and stop. Any advice welcome. (Context: 26F, Diagnosed BP2 and GAD. Currently trying to find therapy because my GP thinks I was misdiagnosed and may have Schizoaffective? Not really sure what this all means...)
