Extreme fatigue l. Laziness fatigue.

I am able to understand ur difficulties. Many of the symptoms which u have mentioned is seen in people with anxiety and depression. In some situations there need not be a reason for it to occur. People try to cope with their low  mood by eating more, sleeping more etc. There is a possibility that depression might b there behind ur laziness and it needs evaluation. Its not ur fault, usually occurs due to chemical changes in the brain. Anxiety can have many bodily symptoms like palpitations, tremors, sweating etc like u have mentioned. V would need to know few more details like ur sleep, hunger, energy levels, interest etc to give appropriate suggestions. Ur problems can easily be treated with counselling and if needed medications. Don't let ur problems affect ur personal or family life. U need a psychiatrist evaluation. U can also consult me online through the Practo chat option. Best wishes for speedy recovery!!
