I guess you're also worried about missing out on things. Yeah it is unfortunate that you missed things but you're old enough now to just do them on your own. Your parents don't need to know everything you do any more.... And I wouldn't worry about marriage anyway. No one goes out looking to get married at your age.

Now for the parents I advise you to tell them how you feel. You need to be straight and tell them how bad the pressure is making you feel. Get graphic. Let them know that you understand that they are your parents and that you "appreciate what they're trying to do for you" (just say it...) but the pressure is becoming too much for you to handle. You have to come to them like an adult and express your concerns. And if they pull the silent treatment you should ask them what they think about it. They are treating you like a child when they do that and this isn't respectful to you. You have to try and have an actual conversation about this.

Don't feel bad about this. You're not happy about your situation but you're taking steps to make it better. You're starting to shape your life in the way you want to and that's something to be proud of.
