Over 40 dating with depression in the picture

I guess I really need to hear how over 40's (getting closer to 50..) manage to start stable and healthy relationships especially when anxiety and depression are involved.

I seem to have been totally unable to even start dating when I tried online. Maybe there are more suitable dating apps or tips?

Unsble to socialise at moment due to depression but even on good days i wouldn't go out to usual hangouts and especially since covid have been nowhere.

How do you do this?
