you are not alone
Hi crazygirl,
I'm so sorry to hear about the death of your fiance.
I think your body's response is appropriate to what you experienced, and your symptoms are (imo) probably anxiety related to PTSD. I watched both of my parents die up close, my father from cancer, my mother (recently) from kidney disease, and I am also in a relationship with someone who has a very severe case of PTSD related to a childhood incident.
I think the most important thing for you to realize is that you are not alone.
Unfortunately PTSD is common in our world, although we sufferers commonly feel isolated.
You should also be very careful about what you are putting into your body, (drugs, legal and not, alcohol, etc) and the patterns you may be developing as ways to buffer the pain.
you need to be gentle on yourself and never forget that you are loved. maybe this will help you through the most difficult times.
