Dear Welcome to HCM We understand your concerns I went through your description. I suggest you not to worry. From the description provided, I don t think you have Severe Aggression . I think it is just anger, which is inherent quality of any irritated person. Mood swings also are common for an irritated person. Here, you have to answer one question. Why are you so irritated? This is not a psychiatric disease. This is disorder and disorders can be cured easily. Please do not try to control anger. Instead, try to alter the perception about anger. Think alternatively. Change the situation of anger, if possible, or change yourself, perception. I think you need psychological counseling and psychotherapy. I am more than happy to help you through telephone. Please contact me through customer care, www.healthcaremagic.com. Hope this answers your query. Available for further clarifications. Good luck. Get well soon.
