Solo grocery shopping

So I recently moved out from living with my parents to now living in a new town with roommates. I’ve never meal planned or done grocery shopping alone. So last night I went to the store and walked around shopping for half an hour talking on my phone to my Mom so she could help me ( is this a good price for ... what else do I need... where in the store might that be...) I also only grabbed a basket and since it was my first time grocery shopping since moving it was quite the arm workout.
