Feeling emotional

I am currently at week 21 and my feelings have been emotional and sensitive. I don’t know why I feel upset over some small things that my husband has done. It’s actually not a big deal to me before pregnancy. But somehow it affects me and I just feel like crying out. My tears cannot seem to stop flowing out. I felt like I have nobody to talk to because people will think I’m crazy and ridiculous, and I still have to act strong and normal in front of others while being upset. How do you all handle your emotions? 😔 how to stay happy? #firsttimemom
