I think knock_knock_who is completely right in that the song is about 9/11, but I also think that Kimya's using 9/11 as a metaphor for life with depression and getting through it with a friend.

if you fall in i'll jump down and touch your face while we're both sinking (stinking thinking) we won't drown you are my friend and what we're doing's too important for our lives to end quite yet

I think this part is about depression or a different mental disorder. "Stinking thinking" is a term used by this famous therapist (Marsha Linehan), and it's basically all these kinds of distorted thinking that people with mental disorders have. It's totally possible that Kimya could have heard the term, since tons of therapists across the country/world have adapted Linehan's methods. So, I think Kimya and her friend both suffer from depression or something and she's saying basically they can get through it together and they both have to keep living because their work is too important. But I think it's also meant more in the literal, as she and her friend fall in the twin towers, like knock_knock_who said--like I said before, I think she's using 9/11 as a metaphor.

this is just a test take it with love and you will pass you will be rewarded if you do your very best nothing ever goes as planned so don't take anything for granted if you do the world will kick your ass

Here she's saying that life is a test and you'll be rewarded (either during your life, like karma, or perhaps in an afterlife) if you are loving and thankful in your life and "do your very best."

So I think the song is basically saying "life is hard, and we can get through it together, because if we do we'll be rewarded."

It's probable that Kimya didn't intend for any of that (especially the "stinking thinking") to mean what I got out of it, but that's what this song means to me. (:
