I know I can't do nothing about it except for think about the memories!

My grandma passed away later year November 3rd due to liver cancer. I was staying with her to help her to the bathroom and in and out of bed and whatever else. The 3rd of last year on Thursday was pretty scary since she was vomiting blood probably due to a.cancer tumor busted or something..dont exactly know. now I do still see flashbacks and stuff and sit worried that I am going to vomit blood too, when I do vomit or something. I do have anxiety and I do keep my mind busy to keep.from thinking about these things. it's hard not to think about her since I was there up until her last breath. I just wanted to tell my story about her to get it off of my mind...she did do snuff.the dentel kind in the yellow can if that is what cause cancer....i am 30 years old. I worry all the time but I am not as bad like I used to was.
