party tonight and im worriedd sick!!

dear friends,
im having a tiny birthday party tonight and i CANNOT sleep (its the night before)

what if
i look fat in my dress and have a big outpouching stomach, or someone says my legs arent great (which they aren't..i just don't have skinny legs)
my breakout cant be hidden by makeup...seriously skin WTF!!!
noone comes
i have that horrible 30-45 min wait by myself while people are 'fashionably late'
the girl who invited herself yesterday is really annoying publicly and i wonder why i invited her in the end
too many people come
people come and they are their usual obnoxious, slightly ungrateful, uncaring selves (one girl i can think of pretty much only....okay 3 but still)
the lady downstairs complains about the noise
i eat too much sugar today when baking for it
i forget something at the supermarket
i run out of time to get ready...or generally
somebody discovers my poor personal care that i hide away eg. my heels are all cracked and dry
my oven burns everythinng
somebody complains that we are only providing sweet food (eg. cupcakes etc)
somebody has a vom/pees themselves (like last time)...seriously also, we're OLD?!

ahhhhhhhhhhhhhhhhhhhhhh
help me..i need support
