Getting tired of my 6 month old...

Hello Mama's! It's taken a bit to post from trying things out but, im becoming so tired of my 6 month old crying CONSTANTLY from 7pm-12am. She wakes up at 6:30/7am and naps about every other hour. Her first nap 2 hours long, the second and third are about an hour long and the rest are small cat naps. Maybe 15-30 min. We have tried bedtime routine, controlled cio, rocking, bouncing, tylenol, teething gel, rockaroo EVERYTHING but she only wants to sleep if breastfed and sleeping with me. And even then she wont stop crying. Im at my absolute wits end. We have tried everything yet nothing works until shes utterly exhausted and even then shes a light sleeper. She HATES her bed. Shes slept in the rockaroo since birth and shes getting too large. I feel bad letting her scream the way she does but even if we hold her its the same outcome at this point. We are both just very, very frustrated. Could use some serious help
