Anxiety Choosing a formula

Hi there! FTM to a 12 week old. I’ve been exclusively pumping and been able to feed LO breast milk. However, I’m freakin tired of pumping, haha! But really. This little machine controls my day and life. I’m ready to begin combo feeding but so guilty giving up so I’m struggling with picking a formula. I did some research and it’s really all over the place in terms of ingredients. I think I’m overthinking it all! :( Anyways, any suggestions on formulas? :)
