Duuuuuude… Ok, so if you have growing spots, nail a few holes in your ceiling to drain the water or else your ceiling will bow and the drywall will collapse. Get a tarp on your roof asap until you can get in the attic to find the leak. Trust me, this is from personal experience. Had this happen to me last year. So sorry this happened to you 🙈

Thank you so much for your help and your post.
