I know how you feel, I used to HATE the summer holidays when I was at school. You're better off than I am. If I were you I would plan my day. I would go to work first, then depending on what time you come home arrange to do something. for example, if you leave work at say, 3pm then go for a drive or do some shopping with friends. If you come home a little late, say 7pm order a take away or cook yourself dinner then watch a movie. I would also try and get a hobby say, running or aerobics. That way your day would be full.
