Two parts of a poem of mine that need criticism?

For starters it doesn't need criticism it's really really really good...second I just have to say that I think I understand what ur poem is talking about basically how as humans we tend to shove ppl we care about, we shove them away...they stand at the doors of our minds or hearts wanting inside but we're afraid to let them in b/c if we let them in they might hurt or destroy us or at least we think they will, that person feels they are left in the cold and wonder if they never had tried to enter if we would really seem to be treating them so cruelly or if it would seem so coldly that they were being treated...that then leaves them knocking at our doors
