I lose branches all the time....$1000 dollars a branch! DO NOT try to pull the branch back up ! Let it be, most of the time it will heal itself. Give the branches some form of support as they are going to get bigger! Some strains require more support than others.Either use a stake and tie off of it or take twine and go from the main stem ( high up) to the branches.Good Luck! PEACE....
