Help I’m dying


My baby turns 8 months old tomorrow: I don’t know what’s going on but during the day she takes her naps just fine on her crib but at night when it’s time to sleep she doesn’t want to sleep there, she wakes up crying and only wants to sleep on my arms or near me. A few teeth of her are coming out, she already got two out plus 3 more coming could that be it? Please help me because I’m not sleeping ok and I feel like I’m going to lose it, my arms and back hurt I can’t take it anymore
