Teething baby driving me NUTS

She screams all day and all night.

No frozen tether, chew toy, wet or frozen washcloth, cracker, pain medicine helps. At all.

No sleep and it’s literally giving me the worst headache and I can’t even think at his point. The whole top of the tooth is already through and I can see it and it’s her first but I don’t know why she keeps screaming for days. People keep telling me once it’s through the skin she’ll be happy. She’s not. Help me
