Hmm Perhaps you have a lot on your mind right now. Sometimes we can lose focus if we have a glaring stressor that is always present on our minds. Maybe taking care of that stressor can help you pay more attention to what your doing.
Just reflecting on when did this behavior start, what changed in your life that lead to this, and this can help you identify the source of where this behavior may be stemming from. This will help you be better able you to take care of it :)

It is a really serious problem which needs attention as you need to consult physician and surgeons so they can suggest you better medicines which will help you to recover from this disease.
