Frustrated...Already

Do you ever find yourself getting frustrated before you have even started? I find myself getting that way right now when it comes to getting a new job. I keep weighing the pros and cons and realize that ultimately there will be more pros, but the initial getting there absolutely sucks. See, I've gotten comfortable with everything having to do with my job. I have a great schedule, great benefits, a boss I adore, I get days off whenever I need them with the exception of holidays, and so on. I want to visit my mom this summer because I haven't seen her in what will be two years in the summer and yet if I get a new job I may not be able to get the time off. And not only that, but I won't have vacation time saved up yet. I have nothing on my resume but that of management in retail. I'm already frustrated and I haven't even necessarily begun the whole looking process. I'm not even sure where to start. My brother said that might be the hardest part. URG!
