The difference in my body from pre-pregnancy to post-baby was night and day. I didn't have the strength, I didn't have the flexibility, I didn't have the stamina, I didn't have the mobility. I felt like I was handicapped.
If I've got Writer's Block it generally means that I don't have that much to say or something's not quite connecting. I have had Writer's Block a bunch of times and it's generally because I'm not able to write down what I'm feeling basically. Mostly, I just need to be alone really, or be with someone who can bring that out of me.
