FTM Breast Feeding

So I'm 31 weeks with my first baby and I absolutely 110% want to breast feed. I'm trying to basically "study" on everything as much as I can before he is here. I'm starting to get extremely overwhelmed and terrified because I feel like there is so much to know. Is anyone else experiencing this/experienced it in the past? Does anyone have any advice? Try to make it as simple as possible because I'm obviously new to being a mommy in general. Thanks!
