This sounds like the „textbook definition“ of social anxiety which is understandable growing up lonely—and not learning social skills which many people take for granted later in life.

Maybe you want to take a look at improving this aspect of your life so everyday tasks like calling a stranger etc. doesn’t cost you that much energy.

For me classic exposure therapy helped in that regard and reflecting on the specific situations that I was thrown into afterwards (calling someone, asking for something in the store etc.)
