Separation anxiety

[Joeypac]

I have a 5 year old Sun Conure that I adopted a few months ago. At first everything was going smooth and then out of the blue every single time I leave the room for 2 seconds, even around the corner she screams until I come back. She Is out of her cage when I come home from work getting 4-6 of play time. I'm trying to find out how to help this and it seems everywhere has different awnser. this forum has been extremely helpful and I'm hopeing there's something I can do or not do to help her calm down abit
