Depression. Please tell me. now a days!

Sir/mam I am suffering from anxiety, I just want to know is my mental health is ok or not. My symptoms are I can't do anything except my bound works, I always feel that I can't do anything. I even can't sleep for whole night, And my days going on resting, as I feel always tired, Even i don't want to bath even in summer. I can't laugh, even in great joke or any good news, Sometimes I become too silent and sometime  over violence even In small things. Wants to cry but can't. Wants to laugh but can't. I am not enjoying my food also.. I thought that meditation will help me but I don't find energy to do that. It's going on since 3 yrs approx Now a days I can't stand for a while otherwise faints occurred, vomiting and blackish view. Now a days I want to leave my family and go where no one with me, human voices now irritate me. I want to be happy and healthy Am I ok or not please tell me. Now a days
