help me get a life

im north london just off the m25 also!

And right there is your reason not to move down here!

20k is absolutely sod all within the m25 mate. Don't forget its not just the rent thats expensive. Everything is!
If your on your own, you would want to be earning a minimum of 25k with no other bills (loans etc) to pay other than your cost of living. If its you and the engine destroyer, a combined 35-40k should see you live comfortably in a flat providing you watch your spending. e.g no take aways every other night and going down the pub.
