I don't get why you got downvoted.
Being alone is not "an issue", as the common status quo of occidental society tries to make us think.
Correct me if I'm wrong but I assume the following about the author:
1. He's an american. You were lucky to be born in a first-world country where you can really get to be EVERYTHING you want. Yeah, even with all the "McDonalds/Starbucks/DumbAmericans" criticism being born here gives you access to many things that 90% of the world population can only dream of.
2. He's a middle-class young man. Society, your family and the people that care for you set everything up so that you can go through this period of your life without worrying about anything else than GETTING BETTER AT THE THINGS THAT YOU LOVE in order to earn yourself a place in society that you will enjoy for the rest of your life.
3. "This same nurse was present when some of my friends came to visit to wish me a speedy recovery from my allergic reaction. After they left, she looked at me and said, “Look at all those friends you have!” " - He can be a cynical asshole as much as he would want, but the fact that he had people that took some time to visit him at the hospital because he was ill (i.e. FRIENDS) also makes him a very fortunate person.
What I'd like to say to the author of this post is this: I don't want to change your mind and I don't care, I just want to tell you what's going to happen next. Ten years from now you will meet someone who didn't have half the things that you have access to now, this person will be happy with his/her life and you will still be bitching about how terrible yours is "because of the government", "because of a significant other(or lack of it)", "because money", "because... because... because...". The day you stand in front of this person, you will see the person that you had been if you weren't just a little pussy and that day you will enter a state of depression that is nothing like you have ever experienced before; definitely not the kind of depression that you are used to see on your teen movies. And that day you will kill yourself... and that's it, that's you.
