Getting Sooo Worn Out

I think I just have too much going on right now, I'm starting to be discouraged. S admitted something profound this weekend. Her big sister was home from college and it brought out some negative behavior. She admitted to me during her breakdown that she would rather not have her sister home at all because it was too hard for her to see her leave. She said she didn't want to let her love in her heart. It was a big revelation, but really hard for me. She has every right to feel this way. She is just a little girl, and she has had constant loss in her life, some temporary and some permanent. Ever since she remembers, her daddy leaves for days at a time. (he travels with work). 2 years after joining our family, her oldest sister goes to college. 2 years later, her other sister goes to college. In another 3 years, her other sister goes to college. Hopefully she'll be old enough to understand more. The death of our dog was devastating for her. She said she is only going to let my love in. Who can blame her for feeling that way? I'm the only family member who has been consistent. S is still coughing, it's been waking her up at night. It seems like it's going away on it's own, so I am going to wait to go to the doctor. It was rough getting back to school after a 4 day weekend. I just wasn't ready. We still haven't started our vision therapy, I feel like such a loser not being able to get that accomplished.
