I don't know that I've posted to you before, but I wanted to say that drugs aren't the only answer to depression. In major cases they can be a huge help, that being said if you can't budget for them right now... Little things like taking a walk, really help. It gets you out and moving. I get that motivation is a problem. So how do you think you could manage that? It's little steps that take you on to bigger ones. A walk may lead to more walks to working out etc. Sounds huge from where you are now, but tiny steps. The endorphins help so much.
Even if meds aren't in the works, don't discount them.
