Chord/Tab song: Troposphere

I've noticed a lack of Steve Burns tabs for quite some time
and I've drawn the conclusion that nobody realises that our favourite
Blue's Clues host released an album in 2003, shortly after he left the show.

So, I decided to add a few tabs of his songs to the internet for all to enjoy.

Intro:
[C] [C/B] [Am] [G]
[C] Sit right next to[C/B] me, a[Am]gainst the glass, w[G]here we both can see
[C] Focus on the gr[C/B]ound, [Am]disbelief of w[G]here we used to be

[C] [C/B] [Am] [G]
[C] What should I do [C/B]now? I'm [Am]upside-down, f[G]ighting with gravity
[C] I'll just lock the [C/B]door, and [Am]they won't know [G]how to find me

[F]I couldn't share it, [Fm]you never saw it [C]coming around
[F]Even the bad parts [Fm]move along [C]better than they should

[C7]
Now I'm w[F]aiting [G]here to [C]dis -[C/B] a - [Am]ppear
[F]Have you ever been so [Fm]tired of your[C]self?[C7]
And I'll [F]meet you [G]here in the [C]Tro -[C/B] po - [Am]sphere
[F]Lately I just [Fm]haven't been mys[C]elf

( short phrase of just C )

[C] [C/B] [Am] [G]
[C] Back here on the g[C/B]round, you're h[Am]alfway gone and the t[G]raffic drowns you out
[C] Driving past your s[C/B]chool, [Am]I grew up here l[G]ooking at you

[F]I couldn't share it, [Fm]you never saw it [C]coming around
[F]Even the bad parts [Fm]move along [C]better than they should

[C7]
Now I'm w[F]aiting [G]here to [C]dis -[C/B] a - [Am]ppear
[F]Have you ever been so [Fm]tired of your[C]self?[C7]
And I'll [F]meet you [G]here in the [C]Tro -[C/B] po - [Am]sphere
[F]Lately I just [Fm]haven't been mys[C]elf

[C7] [Am] [Am] [Dm] [F]
[C] [C/B] [Am] [G]
[C] [C/B] [Am] [G] [C]

I'm having a hard time deciding what the last chord is.
So if anyone has a better ear than I, let me know what you believe it is.
