Japanese to English translation? :D

W-well, I've tried searching a whole bunch of sites and I still haven't been able to find the translation for this one song I really love.

The title is "親.指.の.使.い.方 / Oyayubi no Tsukaikata" by Aiko

And the romanji lyrics:

Heya no akari wa terashitete
Kono naita kao mo terashitete
Akaku natta hoho no tokoro
Hikaru minikui atashi no mizu
Yoyuu wo miseta me no shita wa
Netsu wo motta oyayubi wa
Sore wa sore wa jouzu ni kono namida wo fukitotta

Aenaku natte kara juugohi tachi mashita
Ana aita karada to mousou ga atashi wo tabeta

Yoku battan ja nai no ni
Wagamama shinakatta no ni
Hoshikattan ja nai aishita katta no ni
Gomen nasai wasurerare nai
Gomen nasai

Omoi tsuki no ashi dori wa
Kuse no aru hou he susumu
Tadoritsuita sono basho ni
Hikaru minikui atashi no mizu
Shita kuchibiru kan detemo tsuyoku yubi marumete mitemo
Te ga furetara tachikuramu
Anata he no mantan na MEETAA

Aenaku natta kara ima yatto shiri mashita
Tonari niiru koto ga kono ue nai shiawase datta

Nagusame wo itawari wo mi gamaeshita atashi ni
Douka gohoubi wo “Sonnan ja nai”
Gomen nasai umaku ie nai
Gomen nasai

Hontou no atashi wa setsunasa no katamari
Anata he no omoi wa tsuyoku irareru shirushi datta

Yoku battan ja nai no ni
Wagamama shinakatta no ni
Hoshikattan ja nai aishita katta no ni
Gomen nasai wasurerare nai gomen nasai
Gomen nasai umaku ie nai gomen nasai

Any help at all would be appreciated! D:

Your Thumb
(Literally, "the way you use your thumb", or "how to use a thumb")

The room is illuminated by lamplight
Shining light on my tear-stained face
Water gleams on my ugly reddened cheeks
Beneath my overflowing eyes, your thumb
How nicely, how nicely it wiped away my tears

It's been 15 days since I've seen you
Consumed by this void and my delusions

I wasn't greedy, I wasn't selfish
I didn't want anything, I wanted to love you
I'm sorry, I can't forget you, I'm sorry

The footsteps of impulse
Move in the direction of habit
And where they end up, my ugly tears gleam
No matter how I bit my lip or clenched my fist
I became dizzy when you touched me
It was like my tank was full again

I didn't realize until you left
That there was no happiness above being with you

I guarded myself so well against your solace and sympathy
Reward me by saying "it's not like that"
I'm sorry, I can't explain it, I'm sorry

The real me is nothing but heartbreak
My love for you proved that I could be strong

I wasn't greedy, I wasn't selfish
I didn't want anything, I wanted to love you
I'm sorry, I can't forget you, I'm sorry

I'm sorry, I can't explain it, I'm sorry
