How many times can I break till I shatter?

WARNING: major venting post. I have no intention of writing posts like this often, I just need to get this junk off my chest.

What to do, what to do... it's like one bad thing after another is getting thrown at me right now... like, initially I was thinking "okay, only a couple of small bad things happened, it's cool. life is still good." but now it's just getting ridiculous. it starts with not getting enough hours at work. they have cut back hours for everybody and aren't offering extra. then i come about two breaths short of throwing up a few days ago and felt nauseous all the next day; that was fun. then i find out that that this project i have been working on all week i did completely wrong, and i spent hours upon hours on it. then i find out my great grandma had another stroke and is dying. then i found out both my snails died. then i find out i'm going to have around 150 pages of reading for my classes... every night this semester. then i find out that civil war has broken out in kenya, so the school of ed doesn't do student teaching there anymore. what the HECK is going on???

I really have tried to be upbeat no matter what this semester, but i'm having a really hard time with that right now.

UPDATE: things got so much better. only one snail died, great grandma is going to live a little while longer, and now I'm getting more hours at work than ever before! (both a blessing and a curse)
