everyone deals with depression, to the degree and extent is purely dependent on yourself. can't really gauge your depression to the next person, same thing to happiness. only advice, ride it out, find something you like, do things that you like. everyone has up and downs, so you'll finally get out of your slump sooner or later, time and yourself will only tell.

it always helps to talk it out and advice will always be there to follow you, its your choice if you want to follow it or not.
