I feel so depressive these days

I feel so depressive these days ,I stayed at home ,don't want to go out and talk to  anybody.it seemed that i have suffered from depression. i feel worried and nurvous ,i'm confused to my future .And my parents always quarrel since i was a child , the unhappiness of my parents have influenced me .my father was obssessed with gambling.my mother will cry once they quarreled.I don't know how to improve my life ,and now i was controled by such a bad feeling . i read the inspiration book ,i try to stir up ,but it doesn't work .the present me do not seemed like me .
