The yelling doesn't work - I know you feel bad, but don't go back to pull-ups. The reason I say this is that the pull-ups are too comfortable for her. Instead, go back to diapers. This is not punitive in any way, or trying to hurt or shame your daughter. (What I'm saying comes from my own children's doctor.)
A child cannot be expected to have dry nights consistently until they are at least 4 years old, sometimes a little older than that, depending on their own bodily structure. And that's separate from the night time wetting problems with older children, which has other causes. So being completely potty-trained during the day isn't the same as being potty-trained at night. What our doctor had me do is stay with diapers/big boy underwear while trying to 'wean off' of the diapers. (Addition: My doctor's opinion re diapers instead of pullups was not to stress the child about night time potty training before his body was even ready, including getting up to go to the bathroom, and the diapers let them feel the wetness more than the pullups.) If my son wet the bed in his underwear, the next morning I'd sit down with him while we were taking off his wet clothes, and I'd say to him in my most kind and accepting voice "Honey, I know that you are sad that you didn't have a dry night, and I know how much you want a dry night. But we'll have to put a diaper back on you for 4 more nights, and then we can try again." I had a calendar on his wall, and I would draw a star or put a sticker or smiley face (whatever I had at the time) on the night we could go back to underwear. (Also got him used to looking at a calendar!) Granted, I did not change the sheets in the middle of the night - quite frankly, I'm lucky I didn't have to decide on that - he didn't wake up and tell me he was wet, or if he woke, he didn't wake me up about it. This took away all the stress of him having a power struggle with me - the struggle would have only been with himself. And while his body matured, he wanted the dry nights for himself, not his mommy. It was a badge of honor to him to "graduate" from having to wear those ole baby diapers that were leaky because they were also a little small. (The doctor said to put diapers that were a little small on him too, again, so that he would feel the wetness more.) So what if I had to continue washing sheets - it worked. (I bought two waterproof bed pads so I'd just wash the pad and sheets together, and had clean ones ready to go. Somewhere I read that one mom had a sheet/pad on top of another sheet/pad so that she only had to pull off one and the bed was still made. Smart - I had never thought of that when my kids were young.
Remember that she may not be physically capable yet, and remember that you have until now been engaged in a power struggle with her. Change gears, reverse course, and try this approach. Also, try to relax a bit. It's going to be okay, and most likely, 6 months from now, you'll have dry nights and smoother sailing!
All my best,
