Wanting to switch to formula..

My girl is going to be a month on the 13th and we have been ebf this entire time. However, I am starting to hate it. It’s stressing me out and I feel like I have no time for anything else between all the constant feeding. I’ve tried pumping but can’t produce enough to really help. I’m just ready to be done.. I tried to give her formula a week ago but it made her so gassy and she screamed all through the night so I quit cause I hated seeing her like that. What formula is the best and what is the best way to switch? I tried the Gerber Good Start formula last time and thought about trying the Gerber Soothe if anyone has had any success with it.
