Frustrated

Today im 10w5d and I was in the shower washing my hair when I started to get dizzy, I yelled for my husband but my legs gave out before he could get to me. I fell flat on my ass. My husband keeps telling me not to worry, but I'm freaked out even though in my heart I know the baby is super cushioned in there and feel like I can't do anything for myself. I feel bad he always has to help me with stuff. I just wanna feel like a grown up. I'm so happy to be having a baby but this pregnancy is putting me on an emotional roller coaster.
