Perhaps continue to network here and find more ideas.
Volunteer for a charity with more in-home things. Start a limited one day at a time. Keep connected to family …despite limitations if you can. A small at home job? Look into health issues regarding foot and plan to address.
Marriages are work, but it helps to be civil and adult. There’s a lot out there. A church group?
Keep looking and be kind to yourself. You are worth it.
