I know it's hard but try not to beat yourself up. Even if you'd read 100 books it wouldn't necessarily make dealing with a fussy baby any easier! I personally don't think anyone really has a handle on this parenting thing. We all just make it up as we go along - cross our fingers and hope whatever we do works and if it does keep doing it! And as long as your child has a roof over their head, a nice warm bed, access to food/water, a clean nappy and parents who love them then they will be ok. Just do the best you can - that's all you can do!
