Is she high pitched screaming or low grumbly growly constant noise? If the former, sorry you're just stuck holding/feeding her to sleep/calmness til she gets over it (and she will eventually even if it doesn't feel like it right now). If the latter, you can do @minismallholding's controlled crying suggestion as that type tends to just complain regardless of what you're doing XD

I used to have a pile of research (which I may not have anymore due to being past that stage) basically saying that you don't want to do the controlled crying/sleep training thing if they're distress screaming because it does some undesirable brain rewiring.

Having said that, if you're feeling really angry and frustrated yourself, absolutely put her down somewhere safe (that cot can come in useful for something other than expanding your sleeping space ;D) and go outside where you can't hear her trying to scream the place down and take as long as you need to calm down and get back into a good headspace.

Currently I'm still thinking it's age-related brain development stuff coming to a real head (is that a pun? Sorry if it's a pun aaargh) as she may genuinely be panicking about you never coming back, and that will settle once the brain develops enough to realise that just because she can't see you doesn't mean you're not there and never coming back. If it's that, then what you're doing with all this agonising work is assuring her that you're still bloody there regardless of whether she can see you or not and it's helping form secure attachments that will hopefully last forever as she learns that she can rely on you.

If the screaming is or has become a constant thing perhaps a doctor visit to rule out anything else that might be causing her to carry on like a stuck pig.
