Managing emotions!

I'm 9 days away and I am having such a hard time maintaining focus and being anxious/stress free that I literally cry every time I find myself alone looking at my living room full of stuff. Food's really giving me a hard time too since thanks to all this, my stomach isn't keeping it in. Nervousness just has me shaking all over and taking a relaxation bath basically every 2 hours (it really helps me get focused again). My FH is trying to help keep me calm and stable as possible since I'm epileptic and on Monday I sort of had an episode, but I feel that if I don't worry about everything, no one else will. I'm the one with the whole wedding weight on her shoulders and to be honest, I haven't enjoyed the process these last days at all. All I've done is look at everything that's left undone and honestly keep walking to my room and cry myself to bed. I feel as if everything and anything I do to help or improve things, just looks bad on other people's eyes. As if I can't get anything right/straight these last days... but if I don't do it, no one else does so basically it's me or nothing and no one...but those options aren't enough for anyone. I'm trying my best but I feel I just won't get there 😔
