Relating to my moms death and pain

Okay , my mom passed away September 25 2011 at 1230 pm. Before she passed , she would have these pains that would wake her in the middle of the night and she would puke , she told us that she been dreaming about someone choking her , and we watched 1000 Ways To Die , and we knew thats a way that some people die from , it was some type of dis order that I cant put my finger on right now , but she would have pains almost as horrible as mine as I describe in the rest of story , but she hasnt told anybody about these pains before until a few days BEFORE she passed , now Im worried I might be heading the same direction , right now I have the pain-_-. Ever since then I been kinda depressed and sad. I've been havin dreams about the way my mom died with an anuryism/ hemerage stroke/ Brain dead , and I keep thinking that I have an anuryism , because I'be been having major headaches that sometimes last for 2-3 days , sometimes my pain would hurt so much that I couldnt even be in the light , my dad and uncle said that headaches arent usally suppose to last that long but they said I need to go get my head checked out , but I said Im fine , Im okay , Im good , pain pills dont work and it hurts too much to sleep. is it normal for headaches to do that , or last that long. Should I go to the doctor ? Please comment !!
