[TOMT] Help me find this movie!

What on earth is this movie?!

My friend asked me to watch a movie he liked but I can’t remember the name of it for the life of me. The main character Cole is based off of the writer who is a musician with a similar name (Coleman maybe?) and it follows the last four days of his life before he kills himself. The movie cover is of the main character in a hot tub I think. There’s also a scene of a his coworker crying over his death in her car while eating a burrito. I’m sorry if this sounds like complete nonsense but I really wanna know what movie this is.
