Is it ackward the first day of your new high school?

-i going to 10th grade. and i am like wondering like where am i going to sit a lunch if i don't know anyone. like im going to try to meet people before my lunch time and maybe they'll ask if i want to sit with them, but like what if they don't? and im not use to moving so this is like the 2nd time i have moved. the first time i moved i was in elementary school so it was now big deal. but now its high school....
