I want to sell my flat and make something of my life?

I want to sell my flat and make something of my life? - 1
Added (1). I'm 23 and stuck at a dead end. Been in a dead end job working horrible shifts since I left school at 18.

I bought a flat with my then girlfriend 2 years ago under the help to buy government scheme so I have a mortgage. I want to move away from this run down, degrading town I live in and move somewhere else, travel for a bit, I dunno.

There's going to be people telling me to come back down to earth, family, friends, probably even some of you…
Added (2). Selling my flat will be the hardest thing I know, but how much money will I actually pocket back from it? I bought it for 90k 2 years ago with a 5% deposit (20% government loan and 75% mortgage) after fees and such will I have anything?

I know it's easier said than done but hey ho, apart from that mortgage I've not really got any more ties here…
