Frustrating!

So much for not going backwards huh? I'm so tired of doing so well and getting into a groove and then being knocked down and going backwards about five feet. It's so frustrating, especially because mentally I'm trying so hard to handle everything. Maybe I'm not as strong as I think I am. I just want to do something different, to just do it! To be there already and to stop having things happen that make me want to quit. Can't I just have enough time to find a rythm and it becomes a habit before I'm challenged? So frustrating!
