understimated?

Sometimes I feel very underestimated. The things I do for others doesn't really matter to them, like they're something that would never count. It's unimportant to them. It's something anyone would do. I was simply "lucky" to get the "job"
I feel like I'm not appriciated enough, and even if it's a stupid thing to say I feel that way.
I feel like I'm in the way and that I'm never useful for anything at all. But I guess that without that feeling, I would never truly appriciate it when someone actually does appriciate me. And missunderstand me correctly, I know that the people around appriciate me and care about me but sometimes I get lost in my own thoughts about that. But anywhozzle, I think that if you read this you should tell 1 person or 2 or 3, how many you like that you love them, because that could make their day.
