I was unfaithful

yeah, that's right. Stick to what you DO have. I know exactly what you mean about first-thing-in-the-morning and last-thing-at-night. I know. It's Horrible. Get yourself out of that place as fast as you can. Find stuff to do, stimulating new stuff to occupy yourself now, people to talk to. Keep busy.
Squash sounds like a great idea.
What else? Look constantly for new stuff to do, or old hobbies to revive.

You WILL be happy again. This is just something you have to work through. It's hard, but you can do this.
