What should I do?

Have you been to the doctor? You could be suffering from a medical condition, such as chronic fatigue syndrome, or a psychological condition, like agoraphobia. These conditions can be alleviated, but you have to want to change before this can happen. And, to your credit, you have recognised that you have a problem; this is the first step towards helping yourself. Please get along to the doctor as soon as you can. God bless!
