BPs move at night and sleep in the day. They will drink at night. Obvious you have not had your snake long enough, be patient, things will work them selfs out.
Since your snake is young, try to only handle the snake maybe twice a week at the maximum! Handle her/him when they are active, usually at night! (Same goes with feeding!) Snakes sleep during the day! If I woke you up, I can bet you would yawn!
If you want Her/him to be active sooner... Cover the tank with a towel, early then periodically peek in.
I understand you worried, but you worry is going to stress the snake to much!
Read and ask questions as you are. One day you'll notice questions new people ask are from over thinkers "worriers"!
