You sound like the kind of guy who needs religion to cope. Reality is not good for you.
As many others have mentioned, it seems that your data is not reliable. It seems that you are using correlation, not causation, as a way to infer that atheists are more depressed, angry and suicidal than religious people. Maybe, maybe not. Your data definitely provides no help to get a clear answer. I would question the sources of the study and their methods.
Overall, non-religious people are making greater contributions to advance our knowledge of science so we can overcome the challenges facing human kind (population, limited resources, contamination, diseases, etc). In this regard religious people, especially those fundamentalists and cultic groups, are just a drag.
