I need advice because I’m loosing it😣😣😰

My little one turned 6 months on the 12 recently She’s been fighting sleep so much that she cries and cries. I give her a bottle and rock her even tried different things to get her to sleep without fighting but it ends up with crying she’s been missing naps because she won’t go down without a fight. I’ve tried giving her a hot bath then a bottle to get her to go down easy for the night but it turns into crying for more then 30 mins I’ve done gripe water. And I feel awful because I’m so exhausted from all this crying and screaming she does that at times I just want to cry and rip my hair out.
