Pyaaronepal, i am really sorry to hear that. Depression takes away self esteem, which is the last thing you wanna lose. In my opinion, its the state of confusion, where you fully don't accept that you are sad and can't overcome/win sadness either. Confusion is always bad for body or mind. For example, if you trying to wake up at 6:am and alarm goes off and you turn the clock off to sleep 5 more minutes but you can't fully sleep because you have to be somewhere at 7:am and fear of it keeps waking you up every 30 seconds. That 5 minutes might make you a person without the energy the whole day because you confused your body and mind at the same time (which is worse) for 5 min. My point is, try to avoid confusion. try to fully accept that you are sad and then find out acturl reason why you are sad and say it to yourself that you should not be sad for that reason. For example, girl you like a lot doesn't care about you, 1. Accept the state: I am sad and frustrated  and I feel like I am worthless.  2. Reason for the state:  Girl didn't like me, I feel like nobody understands me or I can't be liked by anybody. 3. Accept that you shouldn't be in that state for that reason:  Just watch I will find better looking girl than that, who understands me. I am better off without that selfish girl,  she could have ruined my life...............This will work as first step to boost your motivation to do things like sharing your thoughts with friends, walking, working out...........etc

Try this it will definetely help you. Best of luck buddy..........
