Do people see you as a negative person?

I'm curious to know if it could be an autism thing for people to see us as negative people or if it's just me as a person. In the sense of complaining and losing my temper easily, well depending on the situation.

Examples: If someone cuts me off in a line. I feel like it's unfair because in cases I would have been waiting for some time then all of the sudden someone just comes up and cuts in front of everyone and all the sudden I'm the one over reacting. Or at work I would do my job and finish my tasks and even help my coworkers when I can, but just because I'm not as extroverted as my coworker they are liked more by our boss even though they do half of the amount of work that I do. So when I complain about it I'm told that I'm over thinking it, or to stop complaining. Sometimes it's even because my face is just neutral, people think I'm mad or upset and they're like you should smile more and stop being so negative. Or when I don't want to go somewhere because it's too loud or overwhelming, and complain about it. There are so many other things that can't remember. Anyway I hope you get the gist. Anyone relates?
