What you are going through is perfectly normal, but please do see about it. It could even be a form of Post Traumatic Stress. But whatever it is, the sooner dealt with, the best mended.

Don't be frightened of medication if that is what is required. I am on anti-depressant medication as well as mood stabilising medication and whilst there are risks, the risks are (for me anyway) no higher than those which are caused by my age and genetics.
