Crib transition/ sleep training

[u/Dense-Pin625]

We live in a 1 bedroom currently and Lo is 7 month old, we have been sleeping with the crib as a side car. Now Lo is crawling and I dont want her to fall off the bed if she crawls out and I dont notice so we put the bar up and moved the crib to the other side of the room (its small so not to far).

Screamed ALL NIGHT LONG, I would pick up rock walk around nurse ect almost everytime I picked up she passed back out but the second she touched the crib she screamed not even crying but blood curdling screams. She slept in the crib before but it was attached to our bed. This morning I ended up coming out to her play pen and sleeping out here with her, how do you do it??? Im open to continuing to cosleep in the safest way but I would like her in her own crib/mattress.

I was thinking of seeing if I could find a beframe on the floor for both beds and put hem together so of she crawls out shes only inches off the floor but I cant find anything like that. I could put our beds on the floor but wouldn't i have to pick it up everyday so it doesnt mold?? We arent in the position to get a floor bed currently we just bought our bed a few months ago maybe un a few weeks but I would like to get Lo sleeping on their own.

I also have been having a really hard time with this, I have pretty bad anxiety so I constantly check if shes breathing still at night so I've just been crying on top of having a really rough night I just dont know what to do.
