Welcome to HCM and thanks for posting,
From your description you are suffering from Humor disorder which is a syndrome of depression
. You will need to visit a psychotherapist or a psychiatrist
for proper assessment and counselling
. You might require antidepressive medication such as tricyclic antidepressants. All you will need is the will to move out of your present state and live a healthy and happy life. If you are the type that is not very sociable, you should learn to start going out and hanging/talking with friends and family members. That will be a good place to start. You might also need to choose a job that you enjoy doing and that makes you derive pleasure from it.
I strongly suggest you consult with a psychiatrist.
Hope this helps
