My DD went through this phase and maybe unfortunately for you, she is only just coming out of it. She is now able to self settle (but only just in the last few weeks) and I can put her down in the cot and leave ehr and she goes to sleep on her own. She's also started to sleep the night through again (yay!!) only a few times so far but we are getting there.
Sorry I was no help, and I know how it feels....
