If I died today no one would notice?

I am 25 years old, I grew up in a decent home, i had good parents and a pretty normal upbringing, at school I was never the popular one, I hardly talked, I was too shy, I didn't have a girlfriend, didn't go to prom, etc. Plain and simple, school sucked for me. After experiencing that I thought I would just move out of the house, after all my parents didn't really care and I didn't have a reason to stay, no friends, nothing. I moved upstate and enrolled into community college, dropped out of 2 years, I was just not cut out for it. I got a job as job selling office supplies to companies, hospitals, etc, over the phone. It's probably the most boring job in the world, I sit in my cubicle all day playing around on my computer. I have no social life at all, I don't even talk to my co-workers, the most I have ever said to anyone there was "can you get that for me please" (I had dropped my pen under his desk). I live in a crappy apartment, and have nothing to look forward to in life. I blame all of this on me, but it has gotten so bad that I am contemplating suicide. Can anyone please help me, I feel as if I died today no one would even notice, not even my parents, since my parents died a couple years ago.
