Japanese translation help?

Before anyone goes "whoa that's way off", this is the first time I've translated a song by myself. This time my partner was too busy so I've been up all night trying to do this stuff. I can't find any written lyrics or a video for the song on youtube so I've been doing this by ear since I know roumaji.

However I only know a few Japanese words all together so I don't know when some words end and begin, etc.

This is what I have in roumaji so far: kimi wa doko made mo (maybe: wo, mo u) ka n te gi ga ma ma de ki ro ga ru ai ga u ki ga shi te ku o (wo, u ?) ka o shi no na ka ni i

This is just by ear so there are probably mistakes, I've put the words I knew together and the rest of the words I heard.

If it does help to know, the song is: Cosmos no naka ni - Morrie
