Top Points! Please answer & Help! A lot of questions about laxative related stuff I need answered please!?

It's possible you may have caused some damage, hopefully nothing long term. My advice is to go see a Dr. no need to panic and stress yourself out because stress makes every issue just a little worse, if you feel uncomfortable telling your parents, start small and go talk to the school nurse and explain it to him/her and they should be able to calm your nerves and let you know what your next step should be. :: )
