I need to live, not just survive.

Today I realised that, when I feel so deeply depressed, I only survive and basically stop living. Everything I do during this time, I do in reaction to something that has happened, and I don't have the strength to start something new.
If I can get the strength to want to start doing something I enjoy, like painting, I will have taken the first step out of this deep hole of depression. Only problem is that this depression drains my will to want to do something constructive.
I need to find a way to "re-fuel" my will, so that I can take that very important first step out of here!
