Ok first off I wanted to say that I personally don't like this photo but that has to do with my own personal issues. Secondly I'm very glad that this IS for suicide awareness month as at first glance I was really thrown off and a bit offended.
HOWEVER despite that, speaking from an artistic stand point and putting emotions aside. I think you did a very good job at portraying these images in a controversial manor however in my own opinion I don't read 'suicide' from this and I think that's what you were going for as it is for Suicide Awareness Month.
I have to say, I do find this picture quite intriguing.
I like how the first picture you can't really tell if it's suicide or not. Symbolism for suicide is the murder of yourself? I also like how the focus seems to be on the trigger; it might symbolize the hesitation, or possibly how ready the person in the picture was ready to end it all. In the second image, I like how the person is smiling, to show that even the happiest of people can have these thoughts. It makes the image a lot more meaningful.
I kind of wished that tears would've been added to the model's face, to show maybe sorrow and guilt for what they are about to do. And I feel like the second picture is missing something; maybe the composition could've been a little more interesting. But that's just my opinion.
Overall, a decent picture that I feel clearly interprets what suicide is and the underlying causes to it. Thank you for posting a good image!
