Is it wrong that I'm using my depression to try and make a girl like me using the nightingale effect.
Why do you want the girl to like you in this manner?
I'm hoping this girl would care about me and comfort me
It makes sense to be attracted to someone nice.   You should make an effort to be honest and be yourself so that she is not turned off when she finds out differently about you.
I don't have time for that, I'm just going to fake being in the gutter to seem as pathetic as possible.
The problem with the nightingale effect is that the affection and love feelings that form do not last. You should be yourself and let her get to know the real you or you may end up hurt in the future.
