Ladies please help me 😭

My sweet baby girl will turn 8 months old in 4 days , last few nights has been absolute hell . She was fighting sleep until 11 pm last night screaming and crying . She dosnt want to eat or drink milk . She has 0 teeth yet . She wants to chew on everything but dosnt want to drink milk .

So is it teething ? Or 8 month sleep reggression ? Or leap 6 ?? Me and my husband are so tired and exhausted . Plz let me know how to make her feel little better . I cant watch her being in pain . She was such a sweet always happy little girl .
