Meeting ex girlfriend...

Hey guys just wanted to come on here and share my story and in addition to that I hope I could get some advice or hear some of your stories. Well first off let me start by saying my girlfriend and I broke up late December this all started after a date we had it was fun we both went home and that was the last time we ever saw each other since then. To my understanding I pushed her away through texting and my depression caused us to miscommunicate. Fast forward to late January I try to get her to see me and fix things but that was too late she had said it was over and that I had ended it and she wasn't going to take me back. Finally now late February she agreed to meet me this Sunday and I am very anxious as to how it will go... I'm not sure what to say or do I am still heartbroken and seems to me she's doing fine. We have not talked in about a week she blocked me off everything except email she said she would message me on Sunday after she was off work in order to meet. I also want to let you guys know last year we also broke up but no communication for a month or so led her back to me and that's how we got back together at that point I was nearly over her but I decided to give it a chance and now I'm back where I was. Important notes.. We are both turning 21 this year, we have been together since 2012 and we both have had our anxiety and depression episodes.
