First of all you’ll have to realise that this depression has become a part of yourself which you have been carrying as a baggage since long and thus to remove this thing you’ll have to do something more than you usually do.
Break this vicious circle. Take the small steps first.
Surely it will take time but it is fair enough to give yourself a chance to come out of that depression with flying colours.
Depression is a curable disease of your mind which affects not only your mind but your body also.
First and most important thing is to tell some one about what your going through. It helps a lot. You feel light hearted.
you have to maintain a routine. A very strict one. Get up early in the morning and go out. See the sun hear the chirping of birds. Go for a walk or a jog. Do this everyday for atleast an hour.
in depression you will always be thinking about it. So you need to distract your mind. Concentrate on the now. Like if your eating food feel the chewing in your mouth. While listening to songs concentrate on instruments sounds. So you have to find a ways to keep you occupied All the time.
play a game everyday. Best part of playing a game is you will be lost in the thought of playing well so you will never think about.
Don’t worry about the comments of other people. When you are in car dogs will chase you and you won’t get down and throw stones at it will you? No instead you move forward so don’t worry if some one tells you something bad like your gaining weight and your turning 30 something like that. Let it go. The most important thing is to stay focused and disciplined. You can do it. Better late than never. Go in to strict routine. No matter what stop drinking alcohol and other fat items. Skip the parties skip the team lunch. You are what you think and do and not what you want to be.
Follow these steps:
See all this as a part of your progress. And make sure that by the end of year you will definately be a lot better person both mentally and physically.
