Dear Welcome to HCM We understand your concerns I went through your details. I suggest you not to worry much. The problem you are facing is not just low esteem but PTSD (Post Traumatic Stress Disorder). Only solace is that your problem is comparatively less to other PTSD. possibly because the accident was not that traumatic. Nothing to worry in this regard. Please try to have positive thinking and do some relaxation techniques. Within a few weeks or so, you shall be perfectly alright. Anger is common with every one. Instead of controlling anger, eliminate the cause. Or else adjust with the cause itself. If you require more of my help in this aspect, Please post a direct question to me in this website. Make sure that you include every minute details possible. I shall prescribe some psychotherapy techniques which should help you cure your condition further. Hope this answers your query. Available for further clarifications. Good luck.
