I would check with a local loft and ask about getting it repaired proffesionaly. You also might want to contact somebody like Atlantic Sail Traders that keep used sails on hand. That gives you a back up for your original if this ever happens again. Also gives you something to use while your original is being repaired.
Next time, turn your bow into the wind more. Your mainsail should not be touching the spreaders when lowering. This will also spill wind from the sail and make it easier to lower.
