I lied to my best friend again
What do you think will happen if you keep this up?
She won't believe me anymore.
I understand that sometimes the truth can be hard to tell. However, it is wrong to lie to your friends. If you keep lying they won't trust you when you need them to.
It sucks, but lies are easier for me.
That's true, but lies are only easier to tell in the short term.  When people find out the truth, as they often do, lies can bring consequences that are much worse that we would have faced if we were just honest from the beginning.  I suggest just telling the truth from now on, and trying to fix whatever issues arise.
