Focusing My Project Further

I've had great difficultly in focusing my project from the massive topic of depression. However in order for me to create a good project, I need to make 'a nugget in which I can explore'.
So this is what I have come up with:

Target Audience:
Persons aged 18-24 making the life changing event/transition of moving to Uni and leaving home. I will aim towards this age range in general and look at how to spot the symptoms and signs in order to prevent a down-spiral. I will be making the issue more public amongst this age group so people can see it's common, encourage them to talk about it and ask for help - and hopefully to let them know where to go and what to do in this situation.

I will touch on the stresses, anxiety and strains that can lead towards depression, focusing in particular on the mildly depressed. (This is the point where you have a choice - you can either get better or sink further into depression) I want to raise awareness about what it is, the severity and how to recognise the symptoms and signs. There are things you can do to prevent this and I will adapt these to a typical student lifestyle.

As it can be quite a negative topic I want to put a positive spin on it in order to maintain encouragement and interest so people will not deliberately ignore this issue.
