Yo man. It's not a secret that you feel loneliness at the top. But if that's bothering you and on top of that you are saying most if not all areas of your life are good then I have some news for you. So in general humans as a species is destined to suffering. Makin the long philosophy short, humans need to suffer to be able to enjoy happiness. From what you are sayin you live a decent life but in the back of your head there's something missing or lacking. And that's the suffering calling you to remind you that "you cant be high all the time". To help you with that personally as I've done it myself , would recommend you to go to an animal shelter as a volunteer and help one day a week. Try a homeless shelter and do the same. Try some empathy with total strangers you won't ever meet, quick example: I was waiting in the line for a cashier and had some items and saw the guy behind me had like tw or 3, probably stuff for his breakfast for work. So I said, go ahead Infront of me you'll go quicker and the guy was like if he hit the lottery that day, said thank you so many times like if I gave him a gold ounce coin or such. Makes you wonder what he's been throu. Try some martial arts but maybe not to get serious hurt but to remind yourself that you are a simple mortal being. I recently try humility with strangers, kinda like one year ago or more I was angry at myself and everyone else, now I do a step back and do stuff more calmly,say more times a day, thank you, sorry, please. Etc. Hope I don't wrote too much and you get the point I'm trying to say. Be gratefull for what you have and try experience some suffering from various sources to remind yourself that you are just a collection of a few atoms and a few lucky situations in the vast galaxy. Did you see the butterfly effect movie? Cheers take care.
