Need to get out of this rut.

Stuck in a rut. Crappy job, no friends, depressed, fat/getting fatter. So far im applying for new jobs. Getting my first haircut in years next week. Buying some nice clothes outside of my normal comfort zone. Got an exercise machine and using it at least twice a week. Got a new book and a book of different puzzles (sudoku, crosswords, maths) so I can at least feel like im having some teeny accomplishments throughout the day. Any more suggestions to help myself overcome this?
