Hi Chino22 and welcome to PC. I'm really sorry you've been suffering so much. I hope that here you will find the support that you need.
I agree with everything Sam2 has said.
See a professional. That's the first step to feeling better. Have you had a physical checkup and seen an endocrinologist? This is information you need to get in control of your life. It sounds like you've developed social anxiety. This is a condition that is treatable with medication. Many people suffer from this problem. Also you probably should talk to a therapist. Your situation has been going on for a long time so you probably need help sorting out your thoughts and feelings.
People cope with social situations in different ways. Even people who seem so confident can be in agony on the inside. Read the posts on this site and you will see how many people look OK on the outside but are suffering internally. You're not alone.
I hope you feel better soon. Post here as often as you need to and someone will be there to listen.
