Some people might scoff at this, but there is a classic book “How to Win Friends and Influence People” by Dale Carnegie. It has basic principles on how to be a good conversationalist and how to build genuine relationships; it’s a book about developing social skills. It’s highly rated on Amazon, and there is an audiobook on Audible. But this isn’t a substitute for a therapist so yes, give that a try, and commit to sticking with it.
