I have literally never cried as much as I do now that I'm pregnant. Before I would let things slide and not let them bother me. I would always have a smile on my face. I was always happy. I had friends to hang out with. Now I have no one. I cry every day. I'm constantly arguing with someone to stand me ground. I'm always depressed and I ALWAYS feel alone. I feel like everyone is on my case and always judging me. I stay in my room and only go out to go to the bathroom, get a shower, or go to doctors appointments. I'm mentally and emotionally drained and don't know how much more I can take
