For me, Day 2 is harder than day 1. Day 1 just feels tired, day 2... is when it seems to hit me. I was nearly in tears this morning, and I didn't know why. Feeling tense and irritable too. It's not as if it's a bad day.
It *will* pass. It *will* get easier. Hang in there Eihwaz. You're worth it. We all are.
