Trump has always rambled incoherently. That isn’t new. His base loves him because he represents selfishness and racism. That is who they are. They don’t seem to care that he is a coward and a nutjob. Rich people love him because he will do just about anything for anyone who will publicly shine his shoes.
He’s a nitwit and he always has been.
Here are a few suggestions:
Volunteer at a soup kitchen or a food pantry
Sign up for a church email newsletter and go there when they are doing pot-luck meals (bring a dish to pass)
If you are into sports, sign up to volunteer as a coach.
Don’t buy all of your groceries all at one time. Buy a few things each time and go more often. Even if you don’t meet or talk to anyone but the workers, you will be around other people.
