Angel doesn't hate you! She's just been traumatized by a squeaking, small, blind, horrifying alien that single handedly stole you away and must assuredly mean to suck out your life blood or control your brain. Maybe even both!
I know, a little much right?
But in all seriousness, I've met so many dogs that think that about small pups (under 3 weeks, when they still crawl and make very undog like noises) that you really should consider that this is her problem. When you said this: That means to me she came running in, gonna see her mom, get some pets and kisses, normally every day stuff. But when she jumped up on the bed, there was a monster in your arms!! It smells weird, looks weird, sounds weird, and is just generally like nothing she's ever seen. So she freaked and ran, and to her horror even when you left the room later, it was still attached to you! Even when the thing is not with you, you still reek of it. At least, that's my take lol. I own snakes and tend to bring home a lot of odd animals whenever I can get my hands on them. What your describing with angel is just like how mine react to snakes! Their more used to my odd habits now, but are still weary of them being around me sadly. I'm not going to tell them how large my snakes are going to get lol.
Try to understand that Angel feels the same way, your interacting with something that is making her very uncomfortable, and you won't stop! She really loves you, but now she just doesn't know what's happened or how she should react. =(
So, the main thing you need to do is assure Angel it's not a alien. Enough desensitization might do it, but only the monster turning into a real puppy does it for some dogs.
To help her realize that even if the puppy is still around, your still yourself I'd take up daily walks, training and playtime, just you and her alone. When the pup won't be there, have angel sleep in your room near you. I'd also feed her her daily food while you and the pup are in the room. If need be, be across the house at first. Any way you can get the pup around her while she is doing something positive, the better.
Also, read up extensively on puppy bite inhibition and socialization. BC's tend to be shy and weary of things they don't know. Your going to have to be very careful how you raise the pup, dogs learn so much from their parents and siblings, doing something wrong could cause problems for the life of this dog . I know humans have raised well rounded dogs, so it can be done, but it's just really hard! If your going to try good luck to you, and read read read!
I'd also advise getting onto a bc forum, their not like cockapoos at all. Get comfortable with new dog owners around you so you can do lots of play dates while the pups still young!
Truthfully though, If I were you I'd be looking frantically for someone that has a litter of same age and size pups to foster this little one. Do you have clubs for BC, aussies, or other medium size herding dogs in your area? You could still visit the pup and bring it home at eight weeks, but it'll be able to get the vital learning only other dogs can provide.
