Hopefulcat, I'm so, so sorry. You've had to go through so much in such a short period of time. Sending you healing vibes.
Mbaby, thinking of you! You're not nuts- having to use the bathroom during the TWW would set my heart pounding too! Maybe this won't work for you, but last time I refused to look after I wiped (TMI). It stopped the heart palpitations, and I felt a sort of strange glee at tricking myself! Seriously, I turned into a crazy person. Wishing you lots of luck on Monday!
Gem, I agree- breaks can be so good for your mental health. We took several months "off" just to think things through, and I hadn't felt that calm and balanced for like, the previous year.
