depressed

Hello there :) I want to know from all of you about what activities you usually do when you get depressed, I think I need to try them out :D I just got fired due to my health condition and some internal affairs in office, so my friends there hate me, my family look me like someone that need to...

I just find it odd how I can be bouncing off the walls one minute, and then getting sad for no reason the next. X_X What do you think causes this??? :starving::deadsad::dispirited::frozen:
