HELP QUICK PLEASE "!!!

i had a freak accident today i had a bit of a lovers tif and my girlfriend to really annoy me snapped my flowering white widow rite in half and pulled it from the soil , the best remaining part is the growing tip with about two branches under about 3 or 4 inches altogether i have placed it back into the pot re watered and added fertilizer and kept it under the same lighting will this re root or am i doomed altogether? i am devasted as i had counted 29 bud points and it was still blooming crazy , is there any solutions to this mess?

im not completley sure but i would have used a root hormone on it to try and get it back....im sure someone will dispute this and give u better advice....but in the meantime....i would kick the shit outa the bitch that did that!!
