Hi Doctor, I am 25 years old. From last almost 3 years, I am suffering from some mental tension. Exactly I do not know what the problem is, but below is a list of how I am feeling- * feeling sleepy all the time. I have been sleeping for about 13-15 hrs now a days * feel irritated whenever I see any eatables. My diet has decreased to a great extent * feel like empty minded all the time * no feeling of joy or happiness in whatever I do * heaviness in head all the time. As if someone has put some 2-3 kgs. Of weight over my head * intense pain in neck and shoulders * feel irritated in talking to others. Want to be alone all the time * mind full of negative thoughts * pain in teeth whenever I eat something * continuous and non-stop thinking on any one topic for over days without any outcome to the problem * feel irritated on seeing any of my study books * feeling very hopeless. As if there is nothing to proceed for in life * body has slowed down. Feeling lack of energy. Weakness all the time. Even for the everyday tasks I need to force myself * problems like constipation or gas or stomachache. Occurs every alternate day And from last 4-5 months these problems have increased so much Please sugest me. What is the actual problem I an suffering from?
