Start to ask yourself why you are feeling so sad.
What is missing in your life?
What could make you feel happier?
Maybe you are tired of the same old thing.
What can you do to make things different?
I hope you will be feeling better soon. Best Wishes.

It sounds like you are depressed, which could be a normal thing if something bad has happened to you recently and if the depression is just for a few days or weeks but if you continue to be like this for a long time then you should talk to a good friend or family member. They could help and if it's necessary maybe you should seek professional help too.

It sounds like you have some form of depression. Can you talk to your parents about it, or what ever your faith is talk to someone at your house of worship? Doctors I would try last because when you see them, their ready with pills , or have you fitted for a straight-jacket. (Just kidding about the jacket) I just want to make you smile. Depression is no joke and can get worse, see somebody to help you. You take care of yourself.

Really, I don't know.
What I do know, is to help you, try eating chocolate.
Chocolate contains anti depressants, it will make you feel a bit better. Also, laughter is the best medicine. Look up a bunch of jokes, then tell them to your friends. When they laugh, it might make you happy. It does to me.
One last thing is to interact with your friends. It always makes me feel secure.
Good luck!
