Thank you for writing. You have put a great deal of time, money and heart into becoming a respiratory therapist. Before you give up on it, I hope you will do more to handle the social anxiety. The anxiety will follow you to whatever you do so you might as well take it on now. I doubt that your folks don’t care about your mental health. It is more likely that they want you to conquer your fear instead of giving in to it.
Medication alone is rarely enough to manage social anxiety. The treatment of choice is medication for at least a while plus talk therapy. I also urge people to get into group therapy where they can get immediate feedback about how they interact with others and tips for doing things differently. Make an appointment with a mental health counselor who specializes in the treatment of anxiety disorders. Cognitive Behavior Therapy is one method that has been shown to have strong positive results.
You can do it. You studied hard to get certified in your profession. That wasn’t easy. If you put the same time and effort into getting comfortable with others, it is likely that you will succeed in that endeavor too.
I wish you well.
