Hello, I can understand the symptoms you mention can be frustrating. Are you under any kind of stress? Are these symptoms throughout the day and interfering in you social and occupational functioning? If yes its possible that you might be suffering from depression. Lot of people these days misinterpret lack of interest to be laziness. I suggest you speak to some family member about it.
