British guy here too, OP, How well can you program? I may have something for you to do if you want.

Apart from the above, When I was 16 I was in the same situation. In a way I am now. At 16 I left school for a year and got sad, no friends or prospects. I ended up working at Tesco and it was horrible, so I went back into education.

Although now I am 22 and back in the same position. I would suggest forcing yourself to look for a job. Don't think you can't do it, just blindly apply.
