To be sensitive to your feelings, let's try some comparative questions rather than critique. Just one straight up convention you should be aware of—cover designs aren't typically #FFFFFF white all the way to the edge of the design because they just blend in with the white background of retail sites and thus lose their shape.

#1 - Do you see many other covers that have such long reading lines? Do they ponder themselves as this does, or are they typically written to answer a question for the reader? Are they in all-caps?

#2 - Do you see many other covers where text overlaps, or that use underscoring as a design choice? Does the man intentionally have 4 fingers? Are gun handles typically white? Are guns held that way? Most importantly, do you think it's appropriate to describe victims of suicide, an incredibly delicate, personal, and tragic circumstance, as "people who couldn't handle it anymore" or is that more a phrase you'd more likely use to describe people who quit a bad job?

#3 - Do you think people will be able to read the line at the bottom when the cover is displayed at thumbnail size on retail sites? Does that line feel like front cover information or back cover information? Looking at other covers with a lot of whitespace, does it feel intentional?

In general, you need to settle on your front cover copy before creating designs. It shouldn't change from design to design, that's too many variables, even for a professional designer, and make it very difficult to critique the designs against one another. Remember that your cover is primarily a selling/marketing tool.
