I followed cources of the VRchat (no VR required) community called “helping hands”. They create events classes, and they have a lot of members with a ton of patience that want to ‘talk’ to you

I’ve also used the best (relatively speaking, it ain’t a great UI) app called “sign language ASL Pocket sign” (Android).

On a side note, if I get old and lose my hearing, I would still know the basics to sign. Which has the ability to change that part of my life.
