I have got to admit when I'm in a really bad mood I will sit and watch MLP:FIM because it really does cheer me up seeing how the ponies act with each other and to quote the show learn about the power of friendship has been helpful for me because I know talk to my friends rather then going it alone. I'm now closer to my friends and I can have a good laugh, so yeah MLP can stop suicide because of the way it can cheer people up but it wasn't written for that purpose.
