Failure.. fact or fiction?

I wonder if I am failing at the things I am doing but am too blind to see it.

Am I really a good teacher? Am I benefiting the kids at all? Am I just a waste of a year of their lives? I know that I try.. I try to teach them a lot more than Science, Math, English and Social Studies.. I try to teach them to think, make decisions, form opinions, voice their opinions, understand, be responsible for their actions, accept consequences of their actions.... and so much more.....
But, am I doing that?
Will I be a teacher they remember in 10 years.... ?
Will I have impacted any of them?
I feel lucky to have the opportunity to impact so many children.. but am I actually doing something?
I try.. but I am worried that I am not succeeding.
I am scared....
I have stories of things that my students do. I am not sure if these stories show that I have impacted them.. or if I am just tricking myself into believing so.
I have letters from my students telling me that they love me and that I am the best teacher in the world... but do they really think so?
Would they be better off if I were not their teacher?

Am I a good friend? I really hope that my friends feel comfortable with me. That they would not be uncomfortable if they needed to ask me for anything. That they know I would really try my hardest to help them when they have a problem.. or even are just in a bad mood. I really hope that my friends consider me one of their good friends. I hope that when my friends are upset I can be the one to help.. to cheer them up.. to make life a bit better....
But.. am I doing that?

Am I a good daughter/sister? Am I as good to my mom and sister as they are to me? Do I do my share in those relationships? Am I being selfish and I just do not realize it....?

I am not sure why I am thinking about this. I am not sure what the inspiration for this post was. Maybe the fact that my bitch boss made me feel like I am not doing enough.. even though I am doing everything that I can. She made me feel like everything that I was proud of was nothing. I was depressed about it for quite a while.... but I recently adopted this "fuck off" attitude. I am trying to not let her get to me. I was, and will continue, doing everything that I can to succeed at all I attempt... but I am just evaluating whether I am succeeding or not....
So.. in my case.. now...
Failure....
Is it fact or fiction?
