Some of us are invisible.

I have spent a lifetime trying to figure out why I am not seen and why some people are....

I refuse to listen (sorry to whoever thinks this) to people who give advice on what to do to be "seen". It's trite.

I know it's rather upsetting and doesn't help your self-esteem at all. I know it sucks and is unfair. I know that deeds that are not acknowledged can really make you not want to bother...

And I have no real "advice" for you except to say that I sympathize. It kind of gets better in the way that you will accept it later in life. (I am not saying that it's inevitable that you will always be like this...please understand).
