Simply not possible

Simply not possible is the best way to say it. I give my all at everything I do, and I am a perfectionist but at the same time I know when something is beyond my capabilities. Recently I ran into a situation which made me feel uncomfortable and maybe a little stress. To begin with I do not like reading out loud especially around my peers but with my kids I work with I will do it and not get to upset about doing so. I would just like to know how someone can expect another person to read a language they have no real experience with, and never took any lessons with, I speak English and sometimes that questionable.
I was reading to one of the children I work with, and they was pointing at the Spanish, so I said Oh I don’t read Spanish only English. Some one told me pretty much read it anyways. I was like well I don’t know Spanish, and got told well try. How do you try to read a language you clearly do not read!!! It’s not like it’s Hebrew or German where I have had more experience and might have a better changes BSing my way through it. How could any one expect me to read Spanish when I never took a class in Spanish, or well frankly don’t speak it, now I do know enough to understand certain letters do not have the same sounds as they do in English. That’s simply expecting to much, there is no way I could accomplish reading Spanish! I guess I am a perfectionist on things I know I can accomplish.
Today I decided to talk to one of my supervisor. Even though I talked to the lead person in the room I still felt stressed out something would show up on my eval in a few months. I was encouraged to day and don’t feel exactly stressed about it and I am starting to make friends at work. Normally I try not to talk to many people when I am new at a company, fear it won’t last long. Now I want this to last a long time, maybe until I move back out west when ever that happens. Its like office furniture once you find a piece that you feel comfortable with you don’t want to get raid of it. I am glad so far I am getting positive things said about me because that means I can keep doing what I am doing and learn how to improve and not feel so worried about losing a job I like.
