Re: Is this depression?
No, it is not depression. We all get stressed at some point in life and have tons of pressure to do well. I've felt the same way and usually with time it just passes. Just try to relax as much as possible (easier said than done I know but try to do something that makes you happy or treat/reward yourself with something).
Depression isn't a passing of a temporary sadness and stress like what your situation is. People with a depression can't just pull themselves together and get better. It requires treatment and medication; which isn't necessary in your case - you're just stressed.
