Afraid of breastfeeding..

Posts like this, makes me so afraid to even try to breastfeed my baby.. I know every child is different but, I'm terrified, because this person posts all the time about how her child is overly clingy, throwing tantrums about not getting the breast (1 yr. old), and won't even let other people hold her.. Someone please tell me every child isn't like this... =/
