vacation alone? bad idea?

I'm so overwhelmed with life right now I seriously just want to getaway & relax. I've been thinking about taking a week off from school, work, & being a mommy. I'm 18 & im just so stressed, I'm trying my best not to shut down because the first time it happened it was horrible. There were mess, mental hospitals, the whole 9 yards. Is vacationing a bad idea? Of course mom is telling me anything could happen, especially since I'm trying to go alone. & it's somewhere where I don't know anyone. I just wanna get away so bad. Should I go or not?
