Need Help On Depression

From what I understand you were doing great in exams etc until 3 years ago & now even though you know the work you don't do well (although I hope that the exams you've jsut done went well!!) - if this is still the case it seems to me that you need to work on self-esteem & positive thinking - so see if there are any personal development, self-esteem or positive thinking classes, groups etc near you. Then work at it & unfortunately be patient with yourself.
