Breastfeeding help

I'm due in 2 weeks and lately I've just now started researching more about breastfeeding and how it's works and reading stuff on breastfeeding pages on fb and it's making me so discouraged. It's my fault, I should have done this a long time ago but I honestly thought it couldn't be that bad. But now there's all this cluster feeding talk, pumping, and when to pump, what a let down is, lip ties, knowing if your supplementing enough, and just so so much more!! I really want BF to work for my son and I so if any of mommies have breastfed or are now that can give me any helpful advice I would appreciate it more than anything!
