You are not a fool. You are sick. It will take time and focused care to get better. It won't happen over night. You didn't get sick over night. Can you take a sick leave from work for a while and consider checking into a hospital. I know that sounds pretty radical but if you had a broken leg would you sit home with pain killers and hope it will fix itself?

It might be worth at least calling your doctor to let him know the meds don't seem to be helping and you are feeling worse not better. It may be too soon for the meds to take effect but if it is getting harder to cope then your doctor needs to know.

I am so sorry this torment continues. I hope you can get more focused care. You need help to deal with the depressive thinking that is dominating your perspective on everything right now. The hospital may be the only place you can go to get the care sooner rather than later. Be honest your doctor. He needs to know.

Hang in there. It will get better. It doesn't feel that way now but it will get better.
