Help! I've created a monster of my one month old?

In the desperation of needing sleep from my newborn I let her sleep in the bed for 6 weeks now. She won't sleep unless she's in the bed with us or even during the day unless she's being held. At this point, I'm ready to do more and get around more and I have no time for myself. I know it's my fault, but how do I fix it? I've tried crying it out, swaddling which she hates, rolling up recieving blankets on both sides and nothing works. Any other suggestions?
