Hi. I do understand your frustration, but sometimes it is better to think about things twice. You can definetly have fun doing not so bad things and things that does not affect on your future.Try to ask yourself why do you have this fear and why you want to do all this? You want to do it because you want to do it or you want to impress others? Turn on your autopilot. Say no. Stay at home. See how it looks like if you miss a party or something. You will see, it is not so bad. Your whole life is ahead of you. You will have so many chances to do all this in your future...
