I think you need a break, urgently... from everything.

Why would I feel nothing even after getting praise from my bosses about my work? Why would I go in even earlier to try to prove to myself that I am doing something worth while after the fact?

To me, it sounds like you don't get fulfillment in your job. Just a guess, but is this the job you always wanted to do? Or did you dream of something else/bigger?

The hours of work and sleep you mention would numb everyone.

If you have the opportunity (and if not, you really need to CREATE that opportunity somehow), take a week off and go somewhere, far away from family and job - and just spend some you-time.

It might be a chance to reflect on what is going on in your life, and if you like the things you're doing/are happening or not. If not, then it's time for a radical change. Even if that would mean getting a lower paycheck.

The fact that you are writing this post proves that you aware that you need to take some action. You can not spend the rest of your life feeling this way. That's not what life should be.

Head into the forest, go the the beach, or anything else you usually like. Find a place that is peaceful and quite. Take your camera, but don't push yourself to use it. Just try to relax and enjoy.

Create an environment where you don't HAVE to do anything, no obligations. If you need to sleep for 3 days, then sleep for 3 days and don't feel bad about it. Your body knows best.

But I seemingly don’t want to help myself but stay in the same rut.
To me, it sounds you do - or you wouldn't have written this post. Staying in the same rut is your own choice. I can imagine there's a lot of pressure (from your boss, from your family) to keep going, but you can't be at your best if you're feeling like this.

Cut yourself some slack - it's obvious you need to.
The most important thing in your life is YOU! Not a job,not family, nothing else. So go back to the basics and try to find yourself again.

The only one that can help you is you. Get away from all expectations and obligations and take a week (or more) for yourself. Doing things you want to do, not doing things you don't want to do. Just BE!

If you can't get off from work, tell your boss you have no choice. Because it sounds like you'll be of no use to him if you keep this going. Don't procrastinate. Do it NOW! Take a break from the world, from everything... and focus on yourself.
