Bad friggin week

Today has been a shitty kind of day. My neighbor next door, the one with the alarm clock issue about a month ago, keeps playing opera music way loud early in the morning and then sings along with it. This is while I'm trying to sleep after being up really really late studying last night, as well as after a big test I took that day before. I was due for a whole good night's sleep. While she has a really nice voice, hearing it bellowing through the solid brick wall at 7:30 in the morning just makes me want to do the thing Ariel had done in The Little Mermaid (where she loses her voice) until my alarm goes off at 9:15; then she can have it back. Morning went as usual after that until I got to biostats. I studied my ass off, hours and hours for that test, and I did horribly on it. My study buddy got an A. What the hell am I doing wrong? I haven't had a life in weeks because of the ochem test friday, the biostats test yesterday, the health test tomorrow I just remembered about an hour ago, and the DAT 2 weeks from tomorrow. I cried for a good half hour after getting back to my dorm today. All this hard work and lack of friends and lack of sleep is getting me nothing, no rewards, no benefits, nothing. All for me to pay $1000 towards applying to something that doesn't even seem worth it anymore. I've done everything for these people, I didn't drop out when my father died at the beginning of Junior year, nor did I drop out when my grandmother died 4 months later, or when my sister was in a serious car accident and ended up with a neck brace 2 months after that, or when my mom was hospitalized for complications from surgery and needed 3 blood transfusions, yep, you guessed it, that same year. Most people would've committed suicide by the end of that. I picked myself back up and got ready for the next blow. The thing that really stung at the end of all that was when the dental schools said "well we see that your father died, but your grades that year are low." That's like saying "we see you were pushed off a hundred-story building, but you broke your arm" as a reason I didn't get in. Assholes.
I completely got off subject there. Oh well, I need a good rant, cry, shoulder to do the aforementioned, and SOMETHING to go right for a change. Maybe this is God's way of saying it's my turn for the lightning bolt to hit me. It's hit everyone else in my immediate family, I'm just waiting to get struck.
I'm going home this weekend. Maybe it'll be a good recharge and 'reset' button for me so I don't lose my sanity before Christmas break.
