<human>: I know I haven't always been very out-going, but when I got to college, I really blossomed. I started to talk to people, joke around, go to mixers, etc. I know a lot of people, but it seems like I'm rather...forgettable. "Out of sight, out of mind" applies perfectly to me. No one ever calls me to do anything or even to talk. I rarely receive any kind of communication that is not a response to something I said. Even when I'm with people, I'm easily ignored or talked over. The people that say we're "such good friends" don't talk to me for weeks (sometimes months) on end. Every social thing I do comes from me having to instigate it--whether it's organizing a dinner or just talking to people.

I know that it's not quantity but quality that counts, but I feel like you have to hang out a lot to grow closer, right? I know that waiting for attention is stupid, so I started inviting myself to everything. I went 90% of the way in all my friendships all the time, but my friends never changed. So I just stopped trying...even now, I don't really get out much, and people really haven't noticed.  

This doesn't bother me the majority of the time, but every few months it sinks back in and I get depressed for a few days. My birthday was last week, and no one said anything at all. I'm not sad that everyone didn't, just that the few people I'm kind of closer to didn't. That hit me hard. It makes me want to figure out what I did wrong...I've been told by someone that I'm "unapproachable," whatever that means.

I do know a lot of people and I have a lot of casual acquaintances. I guess it's just that deep down, I know I don't have anyone to share my secrets with, cry on, have a movie marathon with, etc.

Finally, my questions: am I really that forgettable? Am I just not trying hard enough? Or are people just lame?

Can you condense the text into three sentences or less?
<bot>: I'm pretty much ignored, people don't remember I'm alive if I'm not around. Is this my fault?
