Living Nightmare...

I miscarried on Tuesday the 13th, had to have a d&c, I can't seem to get beyond the trauma of it. I keep replaying over and over and over the events, the preop, the sonogram, telling my daughter, waking up from anesthesia.... Everything just keeps replaying in my head and I burst into sobs randomly. Today I went out for the first time, made a run to Wal-Mart, had anxiety attack while I was there. I got home and took a few hours nap. Husband came home and wanted to go out to dinner tonight because we've been cooped up in the house, I understand him wanting to go but I flipped, I began to cry and was having chest pain from anxiety. We ended up ordering pizza and having our close friends over for movie night instead. Please tell me it gets better???!!! Anyone else deal with this?
