Oes suicide add to the complications of normal grief

Counselling Research HND Level.
My chosen Hypothesis is: Does suicide add to the complications of normal grief. (I would like to compare suicide to cancer in my investigative research questionaire).
Background: The aim of this assignment is to introduce me to principles of research, the skills associated with conducting research and particular concerns for counselling. Research needs a formal proposal of the research to be conducted. Demonstrate existing knowledge of topic issues, any debates, and theoretical considerations. Make use of various databases, books and journals. Attention needs to be given to primary research. Explore ethical dilemmas in counselling research.
Maybe best if I fax you criteria.
