Teenage Girls: I messed up big time, I need your help?? (pretty long story)?

Just hang in there, if she feels the same way you do, she will come back to you, and you will need to be there with open arms, just support her in what she does and show her kindness when she needs it and understanding to, If her feelings are shared with yours, she will be there again, us females just get stressed easy, let her deal, and let the pieces fall in place. Chillax and good luck. My best wishes to you.
