OMG, this is from the 15th? And no one responded? Oh how sad. It's normally such a warm and welcoming and supportive community. Are you okay? Here's how you'll know:
If you can see the humor in nobody responding to a cry for help from someone saying they feel like a nobody, then you're gonna be okay. But if it made you feel even worse, and why wouldn't it?, then I just thought I'd check in on ya, see how ya doin'?
Look at me; at a time of need, I'm a first responder. Two days late. But still first.
So anyway, um, no, I've never felt that way. My mommy loved me too much to ever let that happen. Also I do quite a bit of exploring of consciousness so I've a sense of self as well as a sense of no self which is not quite the same as a sense of being nobody. It's a sense of being. And that might be what you're missing.
Now, be careful. Because there are douchebags on this forum who will actually endeavor to make someone feel like a nobody. I think they do that so you don't have to feel that way on your own. See how helpful the people around here are? But they are actually nothing but scum so if anyone does that to you, you tell them to fuck off.
Don't look towards them to make you feel like someone because they are nothing but crap. Whenever you feel like a nobody, you look inside. We are snowflakes.
