Im going into depression?

I have a middle eastern background. I've lived in the united states for 12 years. I'm 16 at the moment. My family is strict and wants complete obedience. No girlfriend ever. No bad grades. No disrespect. My sisters been getting in trouble for talking to this guy who's of middle eastern dissent.. which isnt as bad... my parents arent really racist but want us to stick to culture... and "our people"... my mom gives me constant lectures about religiion culture... my dad is always annoyed i'm not sure why... i'm the oldest... i'm being bugged about picking a job already... i have many relatives that think too much of me expecting me to be something... it's honestly driving me insane... i constant blow off my friends and i cant tell why... i have mood changes constantly... i've been doing drugs lately... i don't know where or who to turn to now... These cultural ties, family, friends, drugs, everything is driving me the wrong way...
