People here arent tryin to put u down or anything of the sort, but they do and will care more about the snake that u have and its well bein then ur lessons.
and in IMHO, takin care of an animal... whether it be a snake, dog, cat, ect... is hard and expensive. so if u do not have the money or not willin to give up a few lessons to make sure that ur snake is well then u should really think about findin a new home for him/her where u know they will be looked and care after well...
please dont take this the wrong way, and i understand that u are younger.... but u have to make a responsible choice between ur lessons or ur pet....
