I can't save you
Why can't you save me?
I won't save you, because I'm busy saving myself.
I feel like your talking metaphorically, which is something that I understand completely. My life is not perfect and I do definitely have problems, but before you can help me or others, it is you who you should help first, and I admire you for being honest with me.
No, I'm not busy saving myself. I just don't care about you and I'm not good enough to save anyone!
Well that turned for the bad and I was really disheartened with what you said. I do hope you care more with other people even if just a little, as it can also be a part of you saving yourself from being isolated with people.
