Sleep probs

Hey mamas so please no negative comments! We sleep trained my babe when she was about 4 1/2 months with the CIO method and within two days we would lay her down and she would just go to sleep no prob. Well we went on a trip for a couple weeks and then came home and she got sick so she has constantly been off her schedule. Now she will scream for half an hour to an hour weather it’s in my arms, next to me on the bed, or in the crib. Doesn’t matter she fights it. I have no idea how to help her and it’s sad that she screams until she goes to sleep. Again doesn’t matter if I’m holding her or not she will still scream. What are some things I can do, if any?? I’ve tried to get her back on a schedule and she’s done well with her naps but she sleeps in a swing with her naps and I’m not gonna let her sleep in a swing all night. Please help!
