I am sitting on my doorstep in the rain. 12 week old is asleep in her cot. 4yo and 3yo in bed. Husband out for a (much needed) night out. Just found out my dad may have Alzheimer's. I broke my foot falling off the toilet seat where I was standing watering a plant on Wednesday. I have wine and I'm having a cigarette for the first time in years. It's a bit stale and has been in a drawer since a party last Christmas. I am at a low. Why is this the most rebellious thing I can do right now?
