I've been through depression myself, and managed to fully recover and now living a very happy life. I've also seen many friends and family go through depression, some recovering.

I would suggest three things:

[1] Have more social contact, even if it is going out for a walk and saying 'hello' to people.

[2] Do some enjoyable physical and mental activities every day.

[3] Find a motivating goal and work towards that goal every day.

Feel free to email me at cpncrunchhn@gmail.com and I'll be happy to chat with you more.
