feeling anxious!

28weeks now and some days I just feel so overwhelmed. my baby shower is less than a week away and I can't believe it's MY baby shower. like people giving me onsies and diapers. I can't picture myself giving birth or being a mom. I'm A little freaked out!! don't get me wrong, I wanted this and I'm super excited too, but I just have no idea what I'm feeling!! when I see all the baby stuff in our home, it's just weird. like it doesn't seem like stuff for our baby... idk. maybe I'm just crazy!! anyone else feel the same???? just freaking a little!
