This is nothing uncommon or abnormal. So far everybody has given very good advice and I have no additional advice to offer.

I just want to emphasise that this is something that is quite normal and if you follow the advice of what has been given above you will win and regain peace. There are many reasons why we humans have this happen to us. There can be libraries written about it. But, the simplist answer is the best. Life is a trial.

Now a trial is to be faced not feared or hidden from. Follow what you were told, know you have the strength to over come it.
