There may be several reasons for your anger. One it can be a side effect of your medication. Then it can be that you have an undiagnosed unspecified mood disorder that is triggered by treatment with regular antidepressants. As I don't know much about your current treatment, it is difficult to assess your specific situation. You need to consult your psychiatrist about this, so he can evaluate your symptoms.
