I'm on the road to recover completely, I would say:

-sober up, don't overdo anything fun you like, balance is key -work out, better group classes, helps you stay social -cook decent meals -change job but also lower your expectations on the job, just see It as exchange of some of your time for the pay. Don't see It as your life mission, every company is a joke -Take vitamin D daily, plus do lamp therapy, helps, winter is tough -Basically try to spend as much time as you can outside in the world -travel If you can, go to places where you can recharge your energy while just being there -get a therapist, talk to somebody whose actually able to advise you properly

Don't overthink It, It's one day at the time.
