I am the same. I am 26 years old, have been in college since high school, so what, like 8 years? I'm scared to not be in school and have to work. I've also used the excuse of not being able to work because I'm too busy with school. Granted it might be a bit true because I'm a perfectionist and must get A's in every class and it takes up alot of time, but I admit part of it is an excuse because I'm afraid to work.
My solution is that I work with children.. I've been working summers and part-time weekends lately. Only REALLY scary part of the day is when I have to communicate with parents, but other than that, they're just children. They don't judge as much as adults. Don't get me wrong, I still get scared working with children. When I have to plan activities for them, or do a group lesson, I'm way to critical of myself and what the children will think. But in general, I find children WAY easier to work with than with adults.
