losing sensation after closing nipple rings

CALLING ALL GIRLS WITH PIERCED NIPS OR GIRLS THAT HAD PIERCED NIPS.
Okay so I got my nipples on December 27 and took them out a few days ago after my mom guilted me into taking them out. Long story short, my nips closed (very fast like wow) and they aren't as sensitive as they were when they were pierced or before I got them pierced (which was nothing like what it was once they were pierced). So my questions are:
1. Is there anyway for me to ever gain the sensitivity back?
2. Can I get them repierced? 
3. If I do get them repierced, will the sensitivity come back? 
Obviously they get hard when I'm cold or if I touch them after a while, but I almost feel nothing. It's as if they're dead. Like no feeling what so ever. I'm so upset because I'm 18 and I shouldn't even have this problem right now lol. Please help a girl out. Thank you.
