no interest in anything

I feel you. Manicures fitness and socializing becomes a short term motivation in the head for me. I dread the afternoons cause it seems forever to get to night for me to sleep. And when night comes I'll have trouble sleeping. 2 out 7 days a week that I'll wake with a plan determined to pull it through. That too depends on the mental and physical state of my body. My advice is to go with the flow. When the baby's out you'll regret not being well rested and mentally sound for 6months or until u feel confident about you and your baby sync.
