Don't worry... You aren't the only one dealing with parents who cannot understand an introvert. My family is the same way. I get into trouble for not making enough conversation with people which makes me highly irritable or it effects my depression giving me episodes where I feel like I'm a danger to myself.

My point is, you are not alone with these struggles. And other people know how it feels. But sadly, it's a part of life. It would be better if it wasn't though.
