i'm lost. does this song mean. she's wearing a mask/fakeness like everyone else, and she can't stand it anymore and she can't go on living like this.

or life sucks, and she can't go on living/breath through the mask. but other people around her appear to be able to...and she's hanging on?

I believe it's both, and that the song is about your first two words.
