Muller, my advise to you is to go and see your doctor. I have been through the symptoms that you describe following a traumatic event 10 years ago when I had to give permission for the doctors to switch off my fathers life support machine following a blood clot in his brain.
I have suppresed the emotions regarding that event for years and over the last year it has all come out affecting my work and personal life. I went to my doctor a month ago and have started a course of treatment which involves a mild anti depressent and therapy.
I feel much better after having talked about it.
