Metalhead Sometimes things get on top of a lot of people and there are many causes, sometimes all linked together. The tiredness could be physical, you may be lacking something - lack of iron (anaemia ) springs to mind-and when you are tired every task becomes a chore and things get overwhelming. This is when depression can set in, a feeling of worthlessness and the inability to cope with things that you would normally find easy. Its seems you may be at this point now. Please visit your GP and explain your feelings. They will probably do a blood test to rule out certain conditions, or to medicate you appropriately, and you may find that once you feel physically fit again the melancholy will diminish. If not then the Gp should be able to arrange talking therapy along with perhaps short term anti-depressant medication.
