cannot be so selfish think for ourself only.......

Your time belong to you, your family and God if you believe in God. Not your country or company.
I can understand how tiring it is, then on top of that the nuances from parents.
The difference is, I already made that decision, with even less.
Perhaps you can start off by taking half a step.
1. Cut either one of your business. Especially the one that is eating your time up. But don't fill up your emptied out time with the remaining business.
Use that time to rest and do something different.
2. If your remaining business is profitable with a good margin, spend a little and hire a PA to help you with the business. Let PA handle the normal BAU stuff, while you do the decision making and also oversee the business from time to time.
If you don't have the margin to hire a PA, train your team in the business to take over the tasks and upskill them so that they can handle the BAU even if you are not available.
3. Then spend some time with your parents, take them to travel and experience new things together. I don't know whether you notice or not during your 7 years streak, your parents aged significantly. I did.
As much as sometimes you may find them annoying, your time with them is running out.
Last but not least find time to reconnect with your friends and hangout with new people. The reason you want to do this, is to have someone that you can talk to at the end of the day, hangout talk shit and do something together. If you are lucky, you might even meet your significant other.
Hope this helps.
Very well said.
