is there any way to stop this

There’s pretty much every way. Work, eat, shower, sleep is such a minimal place to start that if emptiness is your issue, I feel like you could go in any direction you want and do better.

Maybe no one ever told you this so I’ll try. There is no objective meaning to life or purpose for it. The meaning is up to you to make. I don’t think any path whatsoever (therapy, volunteering, art, hobbies, dating, travel, whatever) will work unless you take responsibility for the problem. If you are hoping for others to provide the genius answer, or looking for some global perfect answer or “meaning of life” then you aren’t taking on the responsibility yourself.

You have to do that or nothing else can work. This thread might be a start. You did ask. Now you need to put the time into the many fine suggestions here.

Don’t take them in turns and try them “to see if they work.” That’s still the main problem of assuming the answer is outside of you somewhere. Instead, take them in turns and put everything you’ve got into them. If you can do this, any of them will work.
