I am not Simon Cowell, although he does look like a dog. I would not see any reason to discuss the suicide attempt. I would suggest you spend time now on your personal essay to focus down the story you've told here and make sure your essay discusses your history of problems briefly, but is more focused on your future and goals. This thread isn't for "What Are My Chances?" posts, and we can't tell you anything much without your MCAT score. However, I'm sure if you post an edited version of this in pre-allo or post-bacc forums, they can discuss options with you there.
