So Anxious!

In two weeks I will be embarking on my new journey (a.k.a. nursing school) and I am so anxious! I waited so long to get to this point and now it seems surreal. I'm excited no doubt but I am also very nervous and a part of me is doubting my decision to make this career switch. What if I go to nursing school and don't like it? I am resigning so it's not like I really have the option of returning to my job, at least not in my current capacity. Or what if I like nursing but can't find suitable employment? It's competitive for every job and nursing is not a guaranteed thing like it once was. To make matters worst, I will probably only be limited to working day or afternoon shifts. What if I fail? A traditional nursing school is known for being challenging and I am enrolled in an accelerated program, while still caring for three kids, a husband and a dog! This is the first time in 14 years that I am going to school full-time and I most certainly won't be the youngest student. I understand that what I am feeling is natural but the closer I get to orientation, the more anxious I get. I just want to get this over with already!
