Hello! I'm sorry you're having such a tough time communicating with people and explaining it to your family. It's hard when your love ones don't realize you're dealing with painful problems.

If your scared feelings are keeping you from talking very much to people outside of the family, then it's probably a good idea to mention this to your doctor. I think you did a good job here of explaining 1) your symptoms and 2) how it's affecting your life. You could tell your doctor the same thing.

If your doctor thinks you have social anxiety, s/he might suggest that you see a therapist who would help you understand why you're afraid. You would probably learn to do exercises or exposures to help you get over your fears. If you were diagnosed with another type of anxiety, you would be more likely to be prescribed medication.

I'll bet that if your doctor thinks you need medication, then your parents will get on board with the idea. However, you may not need it to start working through this. Some people are able to work through anxiety or less-intense shyness as they get older and practice meeting people or having relationships.

It's great that you keep trying even though it's scary and you have thoughts like "I can't think of anything to say" and "I make everyone feel awkward." It could be that you're not acting as awkwardly as you think. It sounds like you're a teenager? That's a time when everyone's behavior is judged really harshly, and maybe you're judging your own socializing by a high standard.

I hope any of this helps. I'm glad you're posting here; let us know how it goes!
