I’ve never thought of myself as a physically strong person. I have weak arms and little endurance. But, I made it through childbirth twice, once without medication. And it was a highly empowering experience. Towards the end of that labor, as I was going through transition (aka hell), I kept saying, “I can’t do this.” And my amazing nurse would say, “But you ARE doing this. And you can do this.” And I did.
So now, when I feel like I can’t do something be it physical, mental or emotional, I remind myself of that. “I am doing this…I CAN do this.” Keep your chin up, nothing worth it is every easy.
