It sounds like you have anxiety. Find a ladies room or some other room where you can be alone when you at work. When you are at home lie on the bed. Give your anxiety time to run its course. Let your feelings surface and face your innermost, difficult feelings. This will usually feel unpleasant but it is not dangerous. After a while, the feelings will subside and you will in the best case, have an idea of what you need to do in your life to make it better.
