When my UC was very active, in order to get my mind off bad symptoms, I would go to a local gym for low level activity or even walk around a large department store, knowing where the bathrooms were at all times of course. Being around other people, even in an impersonal way, was beneficial, along with the physical act of leaving the house.
There are also social groups available that meet once a month you could join. Don't reject groups immediately, you are really just getting out and about
, no commitment for future attendance. Here are just a few at my local library: genealogical, historical (local and national), film watching, knitting, rock-painting, computer skills, photography, helping others to learn to read (children and adults) and of course book clubs. They all bring human contact, some at arms length and others one-to-one. What I like about
libraries is clean restrooms
I'm not a group person (waaay before UC) but joined a local AAUW (American Association of University Women) after attending a meeting and feeling a connection. Along with supporting education for girls and women they have an active social network with local group outings, lunches, etc. It is a tremendous asset for widowed and older women even though about
half are still married, average age mid-70's (I'm younger). A college degree of at least 2 years is required which includes nurses. There are many other groups for you to test-drive and see if they suit you.
Get out and around other people. It will benefit your mental and physical health.
