Well i'll offer some advice then... Those thoughts are pretty normal when you are a teenager. It kinda comes and goes with all of the stuff we have to deal with as teenagers, your hormones are raging, thoughts are racing, and life just sucks.
My advice, just DON'T DO ANYTHING STUPID. i.e. kill yourself. That should be a no brainer. Other than that, you have to work through it. Honestly this website, friends and (kind of) family has helped me in situations of high stress.
Venting like this helps too. I'm sure you already know that.
