I once discovered Love... (the capitalization is to make the distinction betwixt informal love i.e. family/friends versus "true" Love)
...then I discovered nothing will make you bitter quicker than an unrequited Love. I found the worst part of it, is not discovering that no matter what you do your feelings won't be reciprocated, but when you realize that you're not bothered by the prospect of a lonley life.
Yes I realize I'm young (19) and I've got plenty of time to worry about my Love life, but I it's better for me to come to this realization now than have it all of a sudden hit me when I'm in my late 30's (granted I'm still single by then).
But anyway, yeah, I guess I have some people that I deem special to me (perhaps not that "someone" yet, but maybe I have but just haven't realized it yet). It's crucial to Psychological and (arguably) Physical health to have strong social ties, even if it's just one. In sociology I saw a video on social cruelty, and they mentioned all a person needs is one good friend in their childhood to prevent extreme cases in which social cruelty leads to suicide.
