my handwriting changes like that sometimes too, best to let it out on the paper, no one has to ever see it. sometimes i write in spirals and will draw doodles or weird faces. i would write on one page "MAD" or "I AM MAD!" and whatever else bad thoughts anything, to just get it out of your body. then i usually burn or tear up the pages, hide the evidence, lol. it will pass, we have bp, another mood will come!
