Anxiety first trimester

KIMBERLY
Hi everyone. I recently found out we are expecting. I am four weeks. My husband and I planned this baby. Now that I am pregnant I am so overwhelmed and have so much anxiety. I am scared, wondering if this was the right thing, scared about life with baby and just all and all overwhelmed. Last night I got about an hour or two of sleep. This baby is loved and I do have moments of clarity, however having anxiety and being newly pregnant is scary. Anyone else have these feelings, or cannot sleep? Please tell me I'm not alone. Thanks
