I’m sorry ,loneliness is the worst.  My Mom is always amazed that if she goes to church, or a parade and how many people miss her.  Senior center is a great place to meet people.  Hospitals always looking for multiple volunteers, to do a variety of jobs.  Talk to town social worker, they have people that call home bound people.  Try it you could be the caller, you might make some friends.  What are your interests, garden club? Book club?  How about joining a gym, pool therapy would be perfect for you.  I go to the gym many people meet friends there.  Just because your not working doesn’t mean you don’t have alot to offer.  Go gettum.  If you are depressed please talk to your doctor.
