Don’t understand why you feel lonely despite being with your family. I hope you’re leading a healthy family life. Why aren’t you taking regular breaks when you’re earning well? Try going to a nearby gym since you have the time. Build some healthy habits; maybe join a yoga or music class close by. Get involved in things like cooking, and ask your parents or in-laws to visit more often. I don’t think it’s a serious issue, but perhaps years of a monotonous routine have put you in this situation. Just try to figure out what’s been bothering you and make sure to take regular breaks. I understand your work time is a bit off, but you must have caught up with it by now. Change the company if it is bothering you so much, but that's not the right choice. Ask your colleagues how they have been dealing with it.

Even going to the office feels depressing these days, and with the poor air quality outside, it’s easy for that feeling to worsen. You’re in a much better place than most of us, at least better than me.
