I think my new puppy has separation anxiety?

I am in desperate need of some help. Me and my boyfriend just got a new puppy, she is about 2 months old. From the start when we got her, two days ago, she struggled with being alone even if it’s for seconds. We both work hybrid but she will be by herself for 2 full days of the week. Unfortunately, we got her on Saturday and we started work today so there was not much time to adjust her to being away from us. Even during the nighttime, when she is put in the crate, she starts crying immediately when we step away even with the crate covered to make it seem like a den. We know she has just been ripped away from her family but we are feeling frustrated and don’t know what to do. Any advice?
