Hello & Welcome, Adrian. At about your age I made a radical break with just about all I had known up till then. For me it was an exceptionally difficulty but good decision. Consequently I admit my bias in favour of your taking a similar step.

Realise this, even if you succeed - and I sincerely wish you that success - in building a life apart from the people and environments that have nurtured depression, the depressive potential of your past will remain. You will have to remain vigilant. Learn about depression and develop tools to deal with it. Chances are you will need those tools in the future.

Again, welcome!
