What is changing in your view of the world?
I've experienced this with some of my friends who are either approaching or in their 40s and are still living paycheck to paycheck due to either their poor life choices or bad luck. At least one of them is truly in a bad position with kids and driving uber to make ends meet. I used to be able to talk to these guys, but these days when we talk they inevitably get on a soap box and start talking about how they need some government action to come save them from their ****ty choices. I disagree with them heavily on this, but I've learned to keep my mouth shut because they're so blue pilled that they'll attack me as stupid if I try and reason with them.
I've lost the desire to talk to these guys. One of the reasons is that when I see them now, I see myself as I used to be and it makes me cringe. Very few friends will persist in your life over time, this is absolutely normal.
That said, you should resist any and all urge to think that you're better than anyone else, if you're showing pride could be what's causing people to drift away from you. If pride comes knocking, you say thank you and tell that sh!t to take a hike. "There is nothing noble in being superior to your fellow man; true nobility is being superior to your former self"
Do not cut your dad out of your life unless he turns into a true fvckhead, if anything be nice to him and do some cool stuff with him. Have an honest conversation with him.
You getting down about what is happening is on you and only you can fix that.
