He sounds perfectly normal to me, so do try to relax a bit. I know it's because you care a lot

and because you're new at snake-keeping, & you're not yet sure what you're seeing.
We all were new at this "once upon a time". When you get more practice you'll understand his actions & moods much better.

Like his "interest" in you when he's hungry- that's because to him, motion translates to "hey, maybe it's dinner?" LOL Like I said, they see & follow motion & heat signatures, but snakes don't always make good guesses as to what they see. They're not at all logical about what they can realistically swallow, so you have to do his thinking for him.
Watch out for over-feeding! Not sure how big your snake is but normally young BPs are only fed ONE hopper mouse per meal, not 2 & certainly not more, just because they still "act hungry".
Don't fall for that- snakes stay pumped up for food for hours & sometimes a day or more after they eat- it doesn't mean they should be fed more. Best to feed only ONE item of appropriate size/meal.
