Hi Pete, Welcome!
I volunteered on this site, twice, until my eyesight started turning crappy. It helped with my feelings of isolation - a lot! (I lived in the boonies, and couldn't drive anymore)
I now live a lot closer to the city, (All 10K of us) and qualify for different state programs - one I use quite a bit is getting rides to appointments, etc. I'm also in a recovery group, and the interaction with others makes a huge difference.
When I am by myself in the house It doesn't feel bad anymore. I have a medical alert which I wear around my neck all the time; I chat with people online or on the phone, so it is better then it was..
There are great chats here every day; check out the chat schedule!
