FTM and breastfeeding... Still pregnant

I have planned to breastfeed since before I was pregnant.. Still planning to but omg I'm scared to death! I try to do research often, for tips and helpful info, but it's endless and almost everyone I know has given up after a month and gone to formula. Any advice?? I'd rather not hear "it's okay to use formula." I agree formula is okay but I want to give breastfeeding my best effort and constantly thinking about the backup isn't going to help me with my goal. Thanks!!
