If you don't have an aversion to heights, I'd recommend going to a climbing or bouldering gym. Lots of fit and friendly folk with a huge range of personalities. I've all but abandoned the friends I had in uni, they've become lazy self absorbed negative Facebook addicts and femayos who criticise anything that isn't in line with their own self destructive behaviour. Now I hang out with climbers and people who are enthusiastic, go outside, enjoy home cooked meals and the occasional evening out, with positive (but not grating) out looks on life and who have zero tolerance for gossiping or back stabbing. I've never been healthier or happier in my life.  I think you might find the same :)
