Overwhelming day

Today I had my first scan thought I was 12 weeks but I will be 14 tomorrow. They asked me about the Down's syndrome test I didn't really know (yes midwife prob told me but totally went over my head) so we didn't do that as the nurse didnt think we had the relative info. So we told people today although parents knew. I was excited to hear all the family messages through my mum but it's getting to the end of the day and I'm completely overwhelmed by everything. My little secret while I held now is out. Yes you may think that sounds weird it does actually ha but I feel my comfort zone has been invalided. (I suffer with anxiety). To top it all off my boyfriend and I had an argument and he said he was psd off I didnt tell him about these downs tests. I'm just like tell whoever you want in whatever way you want I'm so stressed with even telling people. I'm panicking worrying about everything coming our way. Does anyone else ever feel the same? Feel overwhelmed and uncomfortable? Today has been happy in the morning but just got to me for the rest of the day.
