I feel so helpless today

This is probably my most helpless day ever.Everything today revolves round Microsoft visual basics or mvb and computers( so frustrated with this software ). So in the morning I want to do some assignments with the mvb and so I tried to do it. At first it was okay but then when I reached the coding. (the fucking coding in mvb) so I don know how to type the code, I type what the text in my book has but still errors so I was thinking, maybe I could do the other assignments so I "saved" my work and did it. the other assignment I don know why but I could not enter into the work so frustrated I went back to do the earlier work but it states that I have not saved my work. I nearly slide off my chair. Feel so helpless. Then later and com started moving slowly, have no idea why the reaction time for the mouse is suddenly so lousy, I must click so many times before it enters into another window. So frustrated, I stopped doing it.
So I went to school on the afternoon and it was worse, we have mvb today, and we have to do coding...again. I am those people who are slowing learning. I must go along with the teacher so we are doing the coding and I got so error and I wanted to ask the teacher in charge but instead of all the teachers I got "pink panther". Not to be rude but he teaches so slowly.I think he teaches abstractly. So he takes so much time,teaching me the things I alredy know. And just now...when you do mvb there will be a tool box fixed on the left so I don have it and he is like trying to make the toolbox dock at the left side. And the coding has reached to parts which I don know alredy and he is still finding the toolbox. I was exclaiming in my mind, "OH MY GOD I AM ALREDY SO BEHIND ALREADY, STOP FINDING THE FUCKING TOOLBOX!" Maybe its my fault as I pratice politeness so I did not say anything. I mean he can at least help me do the important things like the coding at least help me say out the code if he has no idea what is happening now...not search for something that's not important at all like the fucking toolbox. So I was following what the teacher says ...until I became loss. I feel so loss because in the first place, my friends sit in front and I sit behind them so I am isolated. I can't ask them all the time, they have their things to do. And such a crappy teacher teaches me. I really feel so helpless. Whatever I do I always do wrongly. People know me...but they really don know me(sorry if its sounds too awful)and oh yeah I got 12 fucking Trojan horses in my thumb drive today...scareee!
