Yes. Seems your girl is more than just cranky to me if it's going on 8 weeks at this point. The biting, the sleeping a lot, the laying down in the middle of the road on walks. Seems something is draining her energy. I'd get her bloodwork done again also. I think that's a sure fire way to start to uncover any physical problem and not have that worry on your mind. Blood work in my area is about $125, not horrible for peace of mind.
If its not physical then you can start behavioral training with her, reteach her all the things she seems to have forgotten.
My Fletcher goes through spurts of that kind of behavior, but it only lasts a few hours or on & off for a day, no longer than that. He's too curious to stay mad. When I can't find him in the house, I just assume he's under our bed. So I open a door to outside or open the fridge or rustle his food bag. Within 15 seconds he's right there! LOL
