Extremely versatile plants, Cannabis is. You can even cut off it's head, and it'll grows two, lol.
That being said, I highly doubt your plant will die. She will mend whatever damage that may have been done and the stilts you added should assist her in doing this. Those that do 'super cropping' purposely break their laterals and stems and the girls come back, so this is nothing! On a side note, and kind of unsolicited advice, is the placement of your fan. I see your leaves are somewhat mis-shapened/pitted a bit and it certainly looks like a symptom of wind-burn. Usually, general, good air circulation in your space will accomplish the same thing. Blowing constant air directly on the girl is disturbing her somewhat and they can get pissy on us😟.
I see you have you lamp at "60 inches" but I'm assuming that was supposed to be cm's? If that's the case, no worries. But if you are literally 60 inches away (5 feet), definitely move her closer! (I'm pretty sure you're implying 60cm though. Lighting looks adequate from the pictures posted👍
Good luck my friend. A little time and little mending and she'll be back in the game, no problem. Any other tips for propping or bracing plants, give me a shout in PM and we can talk further about it. Cheers and happy grows! You're good man👍😉
