Im so scared! Helppp

Basically I was stupid enough to take my case off my phone and got my laptop charger. I heard a thud and of course assumed it was my charger. I went back into my room and later went BACK into the other room to get my drink, I looked down and saw my pink phone. I took it into my room and looked at it. The camera was working fine. But from the side I could see light coming through. At first I thought it was no big deal. But now I am actually REALLY freaking out. Im not the OLDEST so its not like I could take it anywhere and im too scared to do the popping into place thing. Because its not like im getting another phone anytime soon. And I need some type of advice. Could anybody help me in any way? My phone is used and it has a crack at the top right corner. The real place its popped out is near the right in the middle side. And the crack makes it look worse from the side. Im SO scared. And sorry this is so long but I need to be honest so I can find an answer. If you help. I owe you one. Thanks. Also. My grandma kinda doesnt know.... *sigh* ~Cassidy <3
