Hi LGL and welcome!
I am sorry that you are having a rough time with the last increase that was made. This is not uncommon, and as Merrida mentioned, should soon resolve as your body adjusts to this new level.
Until then, here are a few great coping techniques to try, in order to feel as calm as possible during the challeging times.
