Mood Change Again

What a weird day...not sure what kind of mood I am in. The day started out just ok, not really up or down...pretty much just "normal". I felt a big on edge by the time the afternoon started, but I fought the good fight and made it until my second dose of Metadate. About twenty minutes after taking the Metadate I started feeling better. I felt more focused and energized which then leads to happiness...hoorah!
My biggest problem tonight was when I started thinking of the things I HAD to do. Even though they were little things such as, making my son dinner, packing his lunch for tomorrow, and making sure he worked on his science fair project, they overwhelmed me in about 2.5 seconds. I do not do well when I know I HAVE to do something. Why is that? I just get so overwhelmed!
My chest feels heavy and my brain feels bored...trying to watch a movie...just not feeling the best. Where did all the joy go from yesterday...I had a great day yesterday, it was awesome. I get so tired of the mood changes...pure exhaustion! The worst part is going to bed and having no idea how I am going to feel in the morning...it just scares me so much!
