I went to my first party as a new, first time mom, and had to go home because I felt sick to my stomach, but I don't think I was actually sick...

To explain a bit further, it was a New Years party at my brothers house with mostly people that I know. My little man is 2 months old and my mom offered to stay at our house with him for a few hours so we could see our friends. I reluctantly agreed and was even excited at first. We got to the party and I was having a good time and didnt feel weird at all. About an hour in I started to feel really sick to my stomach (I was drinking water) and my legs felt a bit shaky. I told my husband I wanted to go home and so we left super early.When we got home, my stomach ache went away within 10 minutes and I felt perfectly fine. My mom told me it could be separation anxiety. I honestly thought that was a made up term to describe why dogs get sad when their owners leave the house.Could it actually be separation anxiety?? I've never had an anxiety problem in my life! If so, does it get better as your child gets older? TIA via /r/Parenting https://ift.tt/2rRwSTK
