My parents have very high impossible expectations of me and it's annoying me...?

Listen parents mean well but sometimes they can get in their own way when it comes to their children chosing the path they would like to follow. I say look at your options and make a decision. Whatever that decision is stand by it. Do your best and put forth your best effort. When they see you giving it your all parents usually get behind you and cheer. Well good parents do..lol. I believe you have good parents. They just want what is best for you but it's up to you to be strong in your position when it comes to that or they won't take you seriously. They will think....our child is lost and need our help. So get out there and do it. Don't talk about it. Be about it.
