Please, God Lord HELP ME

I’m going crazy!! My 4.5 month old will not stop screaming her head off when it’s time to go to nap or go to bed. I’m living in horrible anxiety and fear that she could break out at any moment. I’m losing my mind. Nothing soothes her. I’ve tried nursing, bottle, paci, rocking, music, gas drops, gripe water, Tylenol, singing, massaging, everything. This has been happening all week long. Brand new. Please someone help me.. I hope no one has ever gone through this but at the same time I hope someone has so they can help me.

I don’t have anyone to help me, I’m a sahm.
