Thanks for the pictures. I'm not very experienced with BP's myself yet, but I'm sure others will weigh in as well. So...that being said...that spot on her neck does look like a possible tick to me. Good chance she has mites as well. There is a lot of old skin that should have been shed off and wasn't. And she looks too thin.

I don't know anything about the place you got her, but petstores are notorious for bringing in imported snakes from Africa that have all sorts of parasites and problems, and then not taking good care of them before they're sold. Looks to me like you may have a fair amount of work ahead of you getting her healthy and thriving.

Did you say you were leaving for spring break? How long will you be gone and what will you do with her in the meantime?

OH, and since we don't know the sex of the animal, I just referred to her in the female sense...not to imply that she LOOKS female. LOL
