Jumping Hurdles?

So even though I've had a pretty good last few days, I don't feel right. And I'm thinking that I'm going through a transitional period in my life. Of course, I am, right? I'm getting married in 40 days. Sure, that's a big thing, but that is the last thing on my mind right now. I'm worried about changing career fields and how to go about it. I plan on going back to school in the spring, but I don't know what to do while I'm there for work. I think it would have to be more afternoon and night work, because the classes run during the day. I've never done that kind of work before, restaurant, retail, etc. , I've always been an AM shift kinda girl. And I guess that worries me, but I'm also very worried about moving into another career. I've been doing this for 7 years, since I was 16, my entire work experience is in the pet care industry. Getting away from that is a little scary to me. But I just don't feel like I used to when I was with the dogs. I feel me losing my patience with them quicker and I just feel emotionally beat up. I think we just have too many dogs that are unstable and it's transferring into me. Not to mention, it's pretty dead end. I make pretty good money for what I do in this industry, but don't let me fool you. That is still not enough to make a living on. That's another reason why I don't have a desire to just try going somewhere else. This was my dream job. And now I know I should have never put it up on a pedestal like that. But at the same time, maybe I'm just feeling like I got over that hurdle and accomplished working what I thought was my dream job. And maybe it's just time for a new hurdle to jump.
