I've been learning new job duties, and I very frequently mess up and have to ask for help.

My coworkers say they're okay with me asking for help, but I'm worried that I'll reach the limits of their patience. I worry that they're only saying that so they can play the good guy in this scenario while I play the annoying, clueless person that everyone hates.

That was basically how it was growing up: not understanding what it was about me that made people reject me. I know somewhat better about what behaviors are not acceptable and I'm trying to avoid them, but I don't really know how to see myself any other way than as someone who will draw out other people's meanness. I feel like I have to work so much harder to be accepted, and I am so far from achieving it.
