I am not strong enough against you
Don’t let me stay without you
I have just come to my senses

[Our Tort System]

I would suggest this for number 1:

I am not strong enough to stand up against you/compete against you

Too long for a lyrics

[Beeesneees]

If they are song lyrics then they obviously need to fit a certain rhythm, and probably a specific rhyme, so it's a little more difficult to offer advice.
However, I won't let that stop me! :-)

I would remove 'stay' and use 'be'.
Don't let me be without you,

Hello

Thanks, Beeesneees.We can't look for rhythm, etc because I translated it from another language.

Swapping "be" for "stay" alters the meaning a bit, though. "Stay" probably indicates that the speaker already is without the person and wants that to stop. "Don't let me be without you" is better if you want to prevent a separation.
