I have almost zero daily social interactions
Volunteer with a cause you support. Very good way to get out of the house and meet people who you know share at least one similar interest while positively impacting the world. Joining local (chapters of) clubs is another way.
They’re out there. Many won’t have overt support for volunteers, but if you call and inquire about volunteering they might say ‘welcome aboard’, or direct you where to go.
Alternatively there are volunteer support orgs such as https://www.justserve.org/ that may help.
