You feel like this because your job is slowly killing you.
Stop working overtime and weekends, and find things to do instead. This won't be an overnight thing, so take your time.
If your job pressures you back into previous patterns, explain to them your situation. If they're still pressuring you, tell them you'll have to start job hunting before they decided to fire you.
You're in a good position in life. 28 is not much, I would have been very pleased to be in a similar situation at that age. Good luck.
