Exhausted

This is so exhausting...does it bother anyone else that breastfeeding is so random and inconsistent ...it is for us anyway. One minute she’s hungry every 2 hours then next it’s every hour. She may nurse for 8 minutes and be satisfied and then sometimes she nursed for 45 and still acts like she wants more. She may want 1 1/2 ounces one feeding and then the next is after 2ozs she’s wanting more. She was just feeding on one side now both is becoming more of a thing. I don’t about anyone else but this is really hard for me. It’s so inconsistent, unlike formula they get a certain amount at a certain time. Does this bother anyone else? It’s starting to really bother me and I don’t know how to handle it. The only way I can think of is trying to just pump and feed her with bottles but I’m not sure that would even be any better.
