2 year old not sleeping

whenever I put my two year old down for bed, she whines and whines. Shes never content when I put her down. Unless its 10-10:30. I dont know what to do. she never wants to sleep even though she is tired. she'll wake up numerous times in a night. I dont let her cry it out but if I go in there and tell her to lay down, she'll cry even more if she sees me. Its now affecting her daytime nap. I seriously don't know what to do guys.. my anxiety is high. Im not getting enough sleep. I know she has to feel the same. I want to put her in a toddler bed but I'm scared to do that. might make the situation so much worse. anyone have any advice?
