Emotions... Why do we have to have them??

I just don't understand why I have to be so emotional. I just want some respect and I never get it. I am battling alot of things right now and am not really sure how to deal with any of it any more. Somedays I just wish I could scream... and others cry. Just want it to get better SOON. I understand that things happen for a reason... but I am beginning to wonder.
