Knowing whether or not the job is for you is important! ^.^ Though you seemingly have the heart, passion, and drive to do it. In many ways it is stressful as ever working short staffed! Just remember that there is something positive with most negatives in life, and that being short can teach you some hella time management skills Try not to be too overwhelmed... the job gets much easier with time, as well as feeling less stressed while short staffed.
