Apathetic...maybe, but I'm not sure.

Yesterday I woke up not excited about school next year. This next year will be my 3rd year of 7th grade. Every time someone finds out I'm a 7th grade teacher they say, "God bless you." I'm a little tired of hearing that. 7th graders are awesome.
Last year I was the only teacher on my team who didn't request a grade change. This year only one teacher requested a grade change, that's good for the kids and the team.
Recently, I had a Principal at one of the Early College HS's say he might pull me to his school. That school is really close to my son's new HS. Before that a Principal at my sons HS said to email her so she can pull me if they have to hire ELAR. I haven't emailed either principal because I like my kids and school, but why is it on my mind daily???
Then I realized I'm going to miss not having my baby with me everyday (that made me cry). Work won't be the same with him gone to HS.
Now...this morning I saw a picture of my 4th & 5th graders that made me miss them, as a whole (they're 700 miles away), but not as a need to teach that age. I got a little teary eyed.
I'm excited to see what the new year brings, but maybe not excited to get back to the grind. I haven't been doing this long enough (only 4 yrs)to not want to do it anymore, and I really love my work and my bad kids that need to be throat punched. But, It was so hard to wake up from Spring Break through summer school and now that it's over my eyes are popping open at 5am every morning. For what?!?! I don't do diddly. I still haven't cleaned my bedroom, school has been out for 3 weeks and summer school has been out for 1 week.
Today I'm having an emotional struggle between joining a gym for the summer or trying for the 10th month in a row to do T-25 in my living room.
This is so unlike me!
I want to say I'm apathetic, but I can't because I don't remember what it means, and I don't feel like looking it up.
I need encouragement, but I don't know why or for what.
