how do I improve my social skills while isolated?

start of with the basics. Stop isolating yourself and start talking to people you interact with. Join clubs. Go to events and talk to people.

You cant get better at things if you don't do them, ie get better at socializing but stay isolated. Gaining more confidence also helps. Pep talk yourself.

your not in a deep cave or in space so theres no reason to be isolated.

you really don't. that's like asking how to retain your gains while not lifting.
