Firstly... HUUUUUUUUUUUUGE hugs to you. That growth spurt was a horror one and like Jodi said, we both had a lot of dramas with our bubs.
I think I just about wore a track in our hallway tiles from all the pacing during unsettled times - but rest assured that it does get better (honest) even if right now you feel like you'll never get sleep again.

Just rest when you can, even if it means taking your bub into bed with you for an afternoon nap cuddled up together (I did this a lot as my DS slept longer this way)

Just hang in, you are doing a great job!
