I think im losing it

37 weeks pregnant and all I feel like i do anymore is cry but I also feel like my husband keeps playing a part in it but I don't know how to cope with my emotions and it's starting to scare me for how I will be after my baby is born. I don't feel harmful just upset with everything and sad. Today I asked to have a conversation with my husband about a dining room table that I wanted to get and just give our old one I got for like $50 when I bout it to someone and he got mad at me and then stopped talking to me so I asked if he would pit his phone down and just have a human adult conversation with me and he told me to go somewhere else then and then left the room. What hurt more was my 2 year old coming up to me asking if I was okay which broke my heart more. So I think that was the icing on the cake and now I just feel sick. Not really a what do I do post as it is just a vent about my life so I maybe don't lose my mind post.
