Stressed and depressed because of school?

I feel so stressed and depressed because of school. I'm now in my middle high school year. My school has this system ; there would be 6 class for each year, 5 normal class and 1class for smartest students in every year. I've got 3rd rank at first year, in normal classes, which means i would be in that smartest class at second year. Now i'm on the second year.
I thought it was gonna be okay, since i passed the first year really well. But i was wrong. I can't keep up with the lesson, esp physics biology and math. I already work hard on them, but still, i'm not better than the rest of "smart" people in my class. I always get 7or 8 (we use number, max 10) but in my class, it would never be enough. Finally, i lost all my motivation to study because all of this smart people. In 1st semester on my second year, i got rank 17th with the average score of 8, 4, and in the normal class, the 3rd rank is in the same average score with me. At first, i want to cry but then i know i got a second chance to fix my rank. Then i work hard at the 2nd semester, and it went really well until the mid of my 2nd semester. I really lost my motivation again, because i study hard for one exams but i only get 8 and almost all of my friends in the class get 9. I'm crying, i feel stupid in the middle of them. I compared my score to my other friends in other class, well my score is higher than them. But it would never be enough. I'm now doing my final tests for 2nd semester, and i already failed on 3 subjects: accountant, physics, and civic education. I know that i wouldn't get 5th rank (that's my target for 2nd semester) since i already failed on 3 subjects. I'm terribly at math and rest of the students too, so i don't really care about it. I really want an iPad or iPhone for my birthday present that would be happen around summer. I think my parents would buy it for me if i have good rank in my class, but i'm not, and my parents will be mad at me and i'll not get what i want. I cried at midnight thinking that i'm not good enough to my parents, and possibility that i would have the last rank in my class for this 2nd semester.
i also hate my friends because they're smart, they're dilligent and they have what i want
i know its too much and i'm such a pathetic for hating people because they're smart. I think i already tried my best but this really makes me depressed, and i'm hating myself because of it.
i don't know what should i do! I can't tell to my sisters because i'm not close to them, and my family is having a "angry" genetic, so they easily mad, angry, and yelled to something/someone.that's why i can't tell anything to my family.i'm stressed, depressed, emotionally drained and angry because of this whole thing. This is stupid. I just want to die or run away from home, or if i could go back, i would tell my teacher not to put me in this "smartest" class.

Should I go for the refurb iphone 5?

I bought a brand new iPhone 5 through Verizon about six months ago so it's still under warranty. Recently the volume down button stopped working. I took it to the store I bought it from and they said no problem and we'll have a new one shipped overnight for you tomorrow. And btw it's a refurb. I was pretty po'd to say the least. I feel that I paid so much for this phone and its under warranty I should get a brand new sealed replacement. The guy behind the counter saw I was pretty mad and suggested I take it to an Apple store and if they can't fix it that they'd give me a new one there. Problem is the closest store is over an hour away. So I don't know what to do. If the refurb was mint I would consider going that route. Any suggestions or if anyone got a refurb from Verizon please help me out.

IPhone 5 recovery mode

So today I was browsing through facebook on my iphone 5, (keep in mind this phone isn't even a month old) and all of a sudden, facebook freezes, so I click the home button, and try accessing it from the home page, and the home page is frozen too. Nothing slides! So I wait about 10 minutes, and still nothing… I try the power button now. And still NOTHING!

I try holding it even longer, still nothing. So I'm left with nothing else to do except put it into recovery mode (holding the power and center button). Now. When I try to plug in my phone into my computer, itunes prompts me that my phone is in recovery mode and needs to be restored in order for me to use itunes with my phone (i don't know why i would need itunes. I just want my damn phone working otherwise i miss work calls.), and after about a 5 minute wait I get this message

The phone "iphone" could not be restored. An unknown error occurred (14).

So I restarted my computer, and did the exact same steps. I get the SAME DAMN MESSAGE!

I just cancelled my contract with telus and switched over to bell for an Iphone 5… And this wasn't even 1 month ago… I'm really pissed off… Can anyone please help me get my phone working again?

Does all car stereo head units with AUX plug have pandora compatibility?

I was wondering if all head units with an AUX plug were compatible with Pandora because I don't want to buy a head unit and it not be compatible. I've read where some will only play Pandora from an IPhone, but I have a Droid Razr M. If not all are compatible it would be awesome if someone would give me a link to where I could see which ones are, and where I can buy one.
