turn back your limb bolts to releive the pressure enough to get the strings off. the bow can be completely disassembled w/o a press by back the bolts out. make sure to go 2 turns top,2 turn bottom and keep repeating. look through the ends of the barrel nuts and when you can see the bottoms of the limb bolts,there'll be enough slack to get the string off. obviously,your cam is junk and will need to be replaced. take a cotton ball and run up and down the limbs. if the cotton snags,your limbs are cracked and will need replaced also.
you can probably replace the bow cheaper than having it repaired. good luck. chalk it up to leasons learned. dont let anyone draw your bow. Welcome to the forum
