Not enjoying breastfeeding... Advice from mamas

So I finally had my baby this week and I'm so in love with her! My whole pregnancy I planned on breastfeeding. I had this whole idea in my head of how amazing and natural it would be. I didn't give formula a second thought. However, now that I'm doing it, it is so stressful and time consuming. I love that my baby loves it and the bonding time between us but we have a latch problem that makes it so painful every single time. She will not open her mouth all the way no matter how hard I try to coax it open so she clamps down extremely hard the entire time. Besides this issue, I have seriously rarely left my bedroom this week due to the constant routine of struggling to wake her up to feed, then struggling to latch her on, then the time it takes to breastfeed, then having to pump.. Then doing it all over again in a couple of hours or less. There's so much time that I could be spending with her rather that struggling and pumping. pumping is so time consuming. I haven't even worn a shirt this week bc of the pain as well as the constant need to take It off to feed or pump. So, now im thinking of switching to formula. I need advice and some reassurance that this is ok bc I do feel sad about it. On another note, I'm worried about the price! Any advice, mamas??
