Help branches breaking in flower

I wouldn’t worry too much about stress.. unless it’s a clean break. If after 48 hours or so, the part above the break is still Alive and the fan leaves aren’t wilted - which will be quite obvious if so - then it’s still alive and will make it. If they’re wilting and dying, clip it off. I run a few strains that get heavy late in flower and have this issue. I’d recommend these plant yo yos.. it’s like a spool of fishing line with plastic hooks you can support several colas with. Amazon search like “plant yo yo hanger” and you’ll get em. Great product to have around. In the mean time, I’d just keep it at about horizontal to the floor if you can find an area that’s open for it to get light and not be up against other branches, and tie it up with string or something maybe. Hope that helped in some way. It’s a good leaning experience honestly cuz purposely doing this will come in handy some time
