I really hear you about the exhaustion as I've been feeling it myself this week. Work related stress (horrors) have done me in. I know I'm retiring but the mutiny that occurred is hurting. I'll get past it but emotional strain can be so taxing.
I can relate to what you are saying about not having to do it all and be a superhero. I guess I'm guilty of that. Thanks for the reminder.
Dating only comes when you're ready. Healing yourself fully is so important. So many people go for the bandaid first without working on the problem so it doesn't leave too many scars. You are a wise man to realize you need more time. But of course - many of life's lessons are learned after the fact. I continue to learn more about myself as time goes on and I make mistakes.
Stay focussed on the good things in your life (your girls, your hobbies etc) and keep your expectations in check. You are a good person and it will all work out when given a bit more time.
