Struggling

Okay, I know I am only in week two of onboarding but I need reassurance that it is totally normal to have no idea wtf I am doing. I study, took notes, watch countless videos, endlessly searched through file owner/highway. I started at a weird time for the holidays and so I feel I didn’t get the best out of my training. Supervisors taking vacations, no one being available to shadow after asking countless people. Everyone training along side me are asking questions I have no idea about and it makes me worried i’m going to miss something. Things are not clicking for me and I’m stuck asking questions that I’m made to feel like I should already know.
