What Causes The Urge To Hurt Oneself While On Zoloft?

Hi, my name is Haley. I have OCD and depression and have been on Zoloft for a year. It works well enough - but there are a ton of things that could be improved upon. One thing I haven t brought up to my psychiatrist is the fits that I have, because I have a hard time articulating it exactly which causes me incredible frustration. However, it s starting to happen so frequently that I think that it may be a cause for concern. When I get mad or frustrated I can t function. It happens more commonly in upsetting situations with my parents. I will sob in my floor for hours, I ll become incolable, and even when I realize that I m being ridiculous I won t be able to stop. I ll have millions of disturbing thoughts and urges run through my head. One that is particularly concerning is that aside from crying for hours I ll have just as strong of an urge to hurt myself or throw myself into walls/hit myself/scratch my face. It s horrifying and I have no idea what to do. Is there a medication I can try? How should I explain this to my doctor?
