Just remain calm . It can be easy to blow things out of all proportion in your mind when you stress and begin panicking . It's a tumultuous time in a new job , things that take an age to do now you will fly through in a few more short months . Your trying hard . You care , that's a good thing . Focus that energy only on what you can control . It will be enough if you get that right .
P.s. Nothing wrong with enquiring where your pay is . It's why your going there after all .
