You most likely have social phobia, a very common anxiety disorder that can be treated through cognitive behavioral therapy and exposure. Medication can also be helpful. The book Quiet would likely be a helpful read.
Hopefully you found this helpful and seek help if it doesn’t start improving through reading about treatment techniques and applying them on your own.

It must be very difficult to be uncomfortable around people when you are self-conscious. Why are you an introvert? I could not say as I do not know you. How long have you been suffering like this? Did it start in your childhood or did a traumatic social event precede your panicky feelings? Are you shy and or suffer from social anxiety? What are you self-conscious about? Your appearance, your accent, your height? You may want to join a group led by a therapist where other people are dealing with similar issues as that may start making you comfortable around people. Or you may seek individual therapy and work through the underlying causes and release them so you can start being comfortable in your skin.
After identifying the lie, you need to become curious about others. What do you do to set them at ease. If you can't see others, your introversion has become selfish.
Sometimes, we have a fear of criticism because we were criticized too much or at unforgettable moments. Who did that to you? Are they still around? If so, tell them how it affected you, or tell them to stop, if they still do it. If they can't, avoid them.
All this is to say find the source and rewrite your script, to include curiosity about the world. You don't want to die not having lived, because you worried about what other people thought. Frankly, for the most part, they don't care. They are too busy worrying about what others think of them.
