Nerves

I know it's all out of my hands. I know that worrying about my thyroid issue isn't going to change either my thyroid numbers or the outcome of this pregnancy. I have done everything my doctor asked of me, including the acupuncture (every single week since July). We agreed that we would give another pregnancy a chance before moving onto next steps. So why am I so terrified of my blood draw today? Like tears streaming down my face terrified.
