Is Breast Reduction Surgery worth it?

Ever since I started developing I hated my breasts I went from a B-D at the age of 13 and I've wanted a breast reduction since I reached over a DD at 16. I'm 22 now with 36DDD/34G after having my son. This is the biggest I've ever been. My back kills me everyday I can hardly get out of bed most days because of it. I'm scared to go under the knife but I can't take it anymore. I don't know what else to do. Is it worth it?
