Sqad, don’t ever volunteer for the Samaritans, I beg you.
Karmlady, your Nextdoor app will have a tab for groups and events, you might find something that interests you. Mine has various singles groups for different ages, support groups, coffee shop meetings, pub quiz teams, casual walking, hiking, exercise groups - even a swingers club. Sewing, bodybuilding, arts and crafts, dancing, litterpicking, walk my dog. You mind find something that interests you.
Check out activities at your local library, too. Mine has coffee and cake evenings as well as book related events, local authors reading etc.
You don’t have to actively set out to meet a man, just expand your social life and get stuck in. I wish you well
