"I want to make a real 40 year old virgin. I want to show the man drinks himself to sleep, wakes up hungover, contemplates shotgun mouthwash every day before going to work and is invisible to everyone around him. His only source of light is the computer screen and the various internet communities where he can be himself and not judged based on his sexual experience(or lack of). That's the only thing that keeps him going, but one day, he drinks a little too much and is pushed over the edge. That tiny speck of hope that kept him going has died out. He pulls the trigger. A few hours pass and he doesn't show up for work. His manager calls and leaves a message saying that he's fired. A few days past without notice, his corpse begins to decompose, and maggots are infesting. The smell seeps into his neighbors apartment. His neighbor calls the landlord. The landlord goes over and knocks on the door and no answer. He smells the stench of rotting flesh so he calls the cops. The cops come and call the morgue, and they bring in the clean up crew. His neighbors to his left and right are shocked, but a few days pass and everything is back to normal, like nothing happened. A funeral is held, with the man's brother only showing up, and they are so far apart he didn't even bother to wear a suit. The body is burned, and the remains are taken to the man's mother, who is blind and lives in a nursing home. She suffers from dementia, and doesn't even realize she still has a son. The brother flies back to Arizona, and he gets reimbursed from his company for bereavement so he doesn't sweat the time off missed from work."

Are there any movies like that? I know about Taxi Driver already.
