I'm just so tired, almost all the time. It's like any little thing tires me out, and the worst part is that it's really difficult to get much of anything done. Here I am with all this grading and packing to do, but all I really can do is sleep. Just taking the dogs out seems to require all the energy I can find, and then I feel like I need to rest for a while. And I'm pretty sure I'm not just lazy, but it's all really frustrating. And I saw the doctor again today; he wants to run more tests of one sort and another. I'm frustrated with not feeling well and frustrated with having to spend time getting all these medical things done. I don't know what to do anymore.
