A need to fix my face...

So tonight at dinner I came across a moment when I literally had to tell myself I was alright and I needed to fix my face. What fixing my face means is even when something isn't going just right I still need to not rain on everyone else's parade with a scowl on my face. So I was sitting out for pizza with my family holding my sprite minding my own business when it slipped out of my hand and landed with a thud (thank goodness still upright) on the table. Everything would be fine and dandy except that was the second time that had happened to me today. I was holding a bottle of lemon juice earlier putting a few drops into my glass of water when I dropped the bottle of lemon juice. The first incident with the lemon juice I chalked up to pure clumsiness...but then tonight it really started to get to me. So I walked over to my grandmother who knows alot about the bodily functions, especially what seems to be happening with me and asked her if it could be linked to my neck. I knew it could because its the same hand that always goes numb when I hold my arms a certain way. Anyway, I'm really saddened/frustrated by it. I'm too young to be going through all of this. But for what-ever reason I am...I have my first physical therapy appointment on the 10th of August. So for now I will chart when I drop things or have the weakness in my arm as I do tonight, and will talk to the physical therapist about it then. I'm praying this is only temporary.
