My grandmother, died when my mom was 10, she had a heartattack as a result of high blood pressure, which they said was caused by stress.

Mom says that (although she did not know this when she died) that the main reason was because she had a child out of wedlock, that she could not support that she had put up for adoption. No one knew except for a few people apparently. That the stress of that, plus everyday life made her have a heart attack.

My question is, is that even possible? :S
I didn’t think you could die from stress..
