Should I stay or should I go? [I Need Advice]

I’m 22, and I’m in college. My parents are pretty overprotective. This summer, a friend from another state came to visit, and we had a great time. I have since made plans to visit her in a few weeks (I’d be flying out of state, and my parents have no idea.) I paid for the flight myself, and I’d be staying with my friend and her parents for a few days. My friend also said she will pick me up from the airport, and she has already taken off work. I feel guilty for not telling my parents, but I feel that I should be able to have independence and be able to travel alone. (I’ve flown MANY times before, just never by myself.) Should I go?
