stress after a miscarriage

Hi I had a miscarriage at 12 weeks a month ago. Ever since my first obgyn appointment when my ob told me that I was most likely having a miscarriage I have been stressed. I stressed all the way up to the miscarriage, I'm still stressed now. The stress has taken ahold of my body. I have dizziness/swaying all the time, up and down blood pressure, near fainting episodes and have lost a lot of work do to this. My regular doctor has prescribed an antidepressant for me to help with the stress. My question is has anyone else experienced this? I feel like there is something else beside stress that is causing this. I don't feel so stressed as i did a month ago. My blood work does show that my Neutrophils (absolute) are high at 7.8. I just feel alone and that people think it's in my head.
