Honest critique for my song

I not very far thru it but anyways here it is:

any opinions or help improving this would be greatly appreciated.

The only real terror

I know you didn't think,
and thats okay,
ill stand behind you,
no matter what they say.

Chorus:
You made a small error,
but tat souldn't get you down,
the only real terror,
is tat you won't come back.

Thanks Guys,
Jules

I think they are ok, good rymes and is fairly easy to put a melody to it. Tried a bit on the guitar and it turned out well.

What bothers me is this ryme though:

I know you didn't think,
and thats OKAY,
ill stand behind you,
no matter what they SAY.

look at the first and fourth line. They aren't symetrical, if you know what I mean, wich is essential for song writing. I can't explain it in a good way. Look up some lyrics you like and look at the patterns they use, it should help.

Also, you can read this guide if you want tips on how to get inspiration and a shortcut to make melodies and puting chords on it.
