Fighting sleep

Hey mamas, I need some help. This week my daughter has been fighting her naps so bad. Only her naps not bedtime. No matter if I’m holding her or rocking her or patting her she screams and screams forever. I have even tried laying with her. I am at a loss and I try not to get frustrated because I know she can sense that and it doesn’t help but it gets to the point I can’t help but be frustrated. I can hardly put her down long enough to go to the bathroom. Idk what to do anymore my anxiety is sky high I’m shaking from crying because I’m so frustrated and feel like I’m failing.. she will be 7 months next week and up until now I used to just be able to lay her in her bed when she was tired and she would go to sleep.
