im sorry everything went so badly for you, i think that first
you should calm down then put all your posters and stuff back
up. when your done tell your parents that cel collecting is
expensive but its something you enjoy, tell them that it means
a lot to you. if they ask you to sell your cels to prove that
there worth something, make it clear that there worth a lot to
you and that you dont want to sell them but would if you absolutly
had to. if you do talk to them be as sincere as possible, dont try
to make them feel sorry for you or be rude when you talk just tell
them exactly what you feel. good luck!
