Am I invisible?

Is there some undefinable thing about me that hides me from site, even on the Internet? Maybe I should explain.....

I'm one of those people who can scream in a crowded room, and no one will hear me. Not even turn their heads. Ok, so I haven't actually done that, so it's only a hypothesis, but I'm pretty sure it would happen exactly like that.
It seems to be the same on the Net. I post something on a forum about the fact that my fiancée just lost his job, and we may lose our home if we can't find another job in this god forsaken town. Someone else posts that their car broke down at night. Who gets patterns gifted to them? The chick who got stranded.
(Please don't think that I'm really selfish.....I don't hold anything against anyone for such a petty reason, but this is my space to explore my feelings and try to make sense of them, so please don't judge me......please?)
I post a wishlist in a RAK group, saying that I pretty much have nothing right now and that I need some help with at least some yarn, and I get nothing. But I look through that thread at everyone else and they've edited their posts, thanking everyone for their gifts. My post seems to be the only one.....Is it because i honestly have nothing relevant to sya in any of the other threads in that group? Is it because I'm wearing black lipstick in my avi pic, even though you can't possibly see that its black but it's a dark color and that means I'm a bad person and un-gift-worthy?
Whats wrong with me? What do I do that makes everyone shun me........I just want friends, people to talk to and care about and not feel self conscious about.......I have a few, but I can never just let myself relax and actually believe that there are people out there who give a damn, and they don't have to respond to every single status on FB, or read my blog and comment, or respond to my post on another site I'm on to show me that they are my friends........

I understand that I am not that interesting. I'm not that pretty, or clever, or smart. I'm not really funny to anyone but my fiance, but thats because i make random meowing sounds that he finds cute........What do I have to do? Who do I have to be to not feel like everyone hates me........I just want to be myself, and I've resolved myself to the fact that I can't be anything other than that, but am I that unbearable?

Hopefully there will come a time when I can look back on this post and laugh at myself. Hopefully when I have people that actually look forward to me posting something, or blogging about some random topic. Sometime when I at least have followers on my blogs, and people who comment.
Or, at the very least, maybe I can look back on this post later and understand my own feelings better........
