Life's too short to live it unhappily. OK, you made a mistake by listening to others rather than to yourself and doing what you truly want to do. So, you may pay a bit for it, but isn't it worthwhile being HAPPY?? Isn't your lifelong happiness more important than a mistake or the ramifications of it? So it takes two more years. You're young, I assume and have the time. As I said, life is far too short to be unhappy. Don't kick yourself. Resolve the mistake, move on and choose the path now that will make you happiest. Cheers!
