It makes me rly moody etc as most ppl but last cycle I was also rly depressed. Like actual can't carry on, wailing in bed, nothings going to go right again, can't concentrate can't sleep not interested in things. Been depressed in the past so i could recognise it and it scared the crap out of me.
Take it easy with the walk, go for longer rather than push yourself to go fast I think. Hope it goes ok, gets boring being at home ill doesn't it.
