I just flamed out exactly as you describe. It's my second time also. If anyone has any tips for some kind of counseling or coaching or anything else, would be much appreciated.

Get a few responsibilities in the outside world, or someone who'll make demands of you. Get a dog.

Half of group therapy is just being in a group. Groups that require you to be rested and fit and provide a local social network orthogonal to everything else in your life include intramural sports, hiking clubs, radio repeating, crafts and markets... and they're all comfortable with nervous individuals showing up.

It's worth being very honest with yourself about what you're feeling. If going into the office fills a void, you should realize that you are now handing a load bearing portion of your life and psyche to your employer. If you are laid off, you will be devastated. Doing the work to get your personal life to a place where you want to work from home because you enjoy your own company, friends, family, pets, environment... is very much well worth it in the long run.
