It was. My employer was so easy to work with. They helped me work within a step-back program, so I didn't return to full-time work immediately.
Stepping back into the real world was wildly difficult. You felt you were being looked at. You felt very “other” than everyone else.
While I still don't know who knew what at what time when I returned to work.... There were new employees I didn't know from when I went off. It was weird. You don't want to bring up this land mine so that you're now caring for someone else's shock about your personal life, and that can make it hard. You also don't want to not mention your child, because they were there and have shaped who you are.
It's a weird spot. Having a bit more distance from the day really did help...practice talking about it and getting used to this new life.
