Why won't my reticulated python eat?!

Hi everyone, my 7 month old tiger retic girl hasn't accepted food in over a month, just wondering what if anything could be wrong? Nothing has changed in terms of set-up, temps, hides, handling etc... When I bought her 4 months ago, she was a monster eater, a big baby, but very nasty, always striking never wanting to be handled, just looking at her would make her pee and poop everywhere. Everything went well for next couple months but now everything is the opposite. She now allows handling with ease, doesn't rush to strike, still quite active, but has now turned into the worst eater of all the retics here. In fact, she now is on a food strike for just over one month. She doesn't want anything to do with food. Doesn't even strike or constrict it, she will just sit still. Anybody have advice for me, she is driving me crazy! Thanks in advance to all who participate in this thread. It means a whole lot.
