Struggling!!

I am struggling healthwise.
Anyone else got an underactive thyroid?
The only good thing is I am losing the weight I put on when my thyroid stopped.
I have twitchy - tingly fingers and a flip flopping heart!
Do I run M2M in September?  The length of Ireland - 345 miles in 11 days.
Weather outside is atrocious today!!
Wish I could take it easy!!

From a tired runner,
Bethany.
