I can really relate to where you are right now, being about the same age and in a very similar situation. I only recently realised I really need help and am also not really sure about drugs.
The way I see them is that they're good for getting back on your feet so that you can perhaps put more into the therapy stuff, which is really the long term solution.
I would maybe suggest going to the library and checking out some self-help books, or buying them if you're more comfortable with that. There are even some that are medically recommended so if you're worried about finding one that's no good there are ways to work it out. http://www.amazon.co.uk/Overcoming-Depr ... 1841191256
This is the one I have and it is really good. The thing is that different things work for different people, so there's nothing wrong with kind of experimenting for a while. Some things just instantly don't click, but some things you have to stick with a bit longer before you can really tell.
Hope you're feeling okay
