Are there any self-help methods for a Schizoid?

I think I share some of it traits. Are there any self-help methods without going to a therapeutic? It will be kind of you if you can share an insight on that.
my personality is like this in brief-:
"I am an introverted person, who loves to be alone. I have my own ways of doing things and I like it that way. But whenever I am in a situation with extroverted people I would lose my balance. I would start blah and it would end up in a way I would never like. I would lose control of everything, and what to say it is very awkward. People often said I used to brag, crack lowly jokes, and altogether act in an immature way."

What is it that you want help with? Can you be a little more specific? Is it that you don't like being so alone or is it that when you're around people you don't know how to act? Or something else?

I agree. There are things you can do and practice, but it helps to know what areas you are having the most trouble with.
