I feel bad asking people for help at times, but people are usually happy to help and sometimes view it as a compliment that you chose them to turn to. I usually try to figure things out first and if I feel it is taking me too long, I will ask someone for help. They usually appreciate that I tried to do it on my own first.

Being new to a position can be uncomfortable for a while and that might be where you feel drained. That might go away once you have been longer in the position.
