Opinions- Should I have a snake?

Get a weight dear so you really know that vital information and can go from there. I still think a vet appointment to check for internal parasites would be a very good thing as well as confirming the snake's gender. Once you've got husbandry sorted out and the snake's been confirmed as healthy, at least then you have a good base of information to work off of.

Don't worry about being worried or paranoid. We all go through it with new snakes. I swear ball pythons come with a free case of OCD. lol
