I can’t know what you’re experiencing. I’ve tried to imagine what I would do. I’m not a pet person so personally, I would never get an animal. I think I would join a tour group and travel with other people. Maybe start with small trips - like New England in the fall to see the leaves. Then travel to Europe with a tour group. Maybe go on a cruise with a group.
I know there are some good travel companies who arrange everything. I’ll bet you’d meet some nice people and have some great experiences.
Another idea, maybe get an RV and travel to see family that you haven’t seen in years (cousins, siblings, etc). The nice thing about an RV is you wouldn’t have to put people out when you visit. You could spend time with them as you wish, then retire to your RV to sleep.
Anyway, I think the idea is to get out of your house.
Do you have any hobbies? Join a line dancing group, or a hiking club.
Loneliness can cripple you, if you let it. I hope you find a way through this and feel better soon.

What about me? 😉
