I have no easy answers, I'm sorry but I do have a couple of observations ..... RELAX AND BREATHE!!!
If the beginning of you SS is when Lucky was Dx then you really haven't been dancing all that long, sorry.
I realize all this testing is giving you good data but it isn't helping you or even Lucky at this point. This is pzi not one of the L's once you figure out his nadir, which keeps moving ..... you are just adding stress to you and to Lucky. Testing is stressful and at the speed that you are doing it, it has stressed you out and maybe Lucky?
I just wonder if you relaxed and let it flow .... do the PS tests and a +4 or +6, changing out when you do it. You need to slow down and take it one day at a time with the belief that it will work out because you are doing what you are suppose to be doing, except taking care of yourself.
My family and I found ourselves in the same boat, only I'm so paranoid that my Payne will? she has DKA 4x and goes south very quick .... so I'm reluctant to leave her with anyone, so we planned a mini vacation close by and took her with us .... it worked out really well. Just those few days helped my mind and everyone enjoyed having the cat around.
Whatever you do, I really think you need to slow down and smell the roses, maybe let Lucky smell too

One of my mentors here kept reminding me in the beginning that this is not a sprint but a marathon and to not get discouraged ..... it was good advice and I pass it on .... thanks Hope! (mentor)
Good luck and I know Lucky's name but what is yours? It will all work out, really.
