9 months sleeping

Background: my daughter has always had trouble going to sleep but laterly got worse.

About 3 weeks ago she was taking 2 naps up to 2 hours and sleeping 8 hours through the night waking up once for her bottle. Now she won't take naps i got to fight her even tho i know she is tired. Bedtime i got to rock her to sleep its like she forgot how to put herself to sleep. Once she is asleep she is waking up nearly every 2 hours. She learned how to pull herself up and crawl. When she does wake up she standing up in the cot and cry till i come in to lay her back down or rock her back to sleep. I'm so tired at this moment i put her to bed at half 6-7 and she is still fighting/crying at me. I'm so tired i just want to sleep.

I dont know how to make it better or is going to get betrer. I must be doing something wrong.

I'm so confused what to do.
