It's just summer babe. Relax. It goes like this:
Jan 2- spring break: banging
Spring break: meh
After spring break to end of school: banging
Summer: sell in May and walk away unless you tour or have steady regulars
Beginning of school to state fair: banging
State fair: depends on the year
After state fair to thanksgiving: banging
Thanksgiving: take the week off
After thanksgiving to mid December: banging
Dec 18-Jan 1: vacation (seriously)
Jan 2 etc.
If you budget properly on the great periods, the slower times are no sweat. I'm super sorry you're struggling but just hang on babe.
