WHY??? Is it supposed to be this hard?

My daughter is almost 8 weeks old. Feeding her is straight hell! Is it supposed to be this hard? Slow flow nipples to slow for her, she fussed about thst. I switched it. She is formula fed. She chokes on it or she vomits everywhere. She drinks it to fast...or shes drinking to slow. Its seriosuly to the point where I dont trust anyone including her father to feed her correctly..because its even hard for my self to feed her. It cant be like this. I go back to work on monday. Her father and my mother will be watching her. Shes not like feeding other babies. Shes IMPOSSIBLE TO FEED. Ive tried everything. Burping often during a bottle, switching bottles, nipples, fornula. Holding upright for 30 mins. Which my husband is not going to do when im at work. I spend up to almost an hour make sure she is fed correctly. I feed her..Then she chokes..then i burp her she fights the burp and then i try feeding her again and then swatting the bottle away. And then she chokes cause she gets so upset. HELP ME . IT CANNOT BE THIS HARD.
