freaked out!!!!!!!!!!!!!!

i think someone tried to break into my apartment!!!!!! earlier this morning around 11:45 i was sitting at my computer doing whatever and i heard someone try to open my door, like 5 or 6 times....it was closed and locked and everything....no one knocked and they left after a few minutes.....i thought maybe the mailman, but when i opened my door a few minutes later there was nothing wedged in my door and no box...no one was there and when i had opened my door to go outside the door had been pushed forward so someone had really tried to get in m apartment....it really freaked me out.....i called the office and they told me to file a police report so i called them and they came....i'm really freaked out now....my anxiety is so high and i'm crying because i'm so freaked....
