We all go through periods of time where we struggle and second guess and question our very existence at times. You do good stuff here at PC. Maybe not all the time, do you find it your best, but it's good. It's ok that you also need time for yourself, but don't quit this great site that does help you and gives you a place to support others.
It's a long process, but it's a good one. It's a good path you're on...stick with us.
