Am I right to be mad?

Ok, so here's my situation:

I have recently lost a lot of weight, and I know some people were worried about me, but I am not losing weight anymore and I am not anorexic.

My mother, who is a psychologist, had to write an article about anorexia, and I helped her with it by making it sound more like if a teenager had written it, but that's pretty much all I did. After, she sent it to a few friends on the net, as she alzays does when she writes articles, and said "written with the help of my daughter". But I didn't want her to do that, and I only noticed when I received it myself. I wasn't happy about it at all and I told her because I knew that some people were going to come to me and say I don't know what (I have already had some really rude comments in the past and now that it was getting better, I didn't want it to start all over again), but it was too late and she said that anyways, people who received this e-mail were people who knew me and blah blah blah. But then today, I got an e-mail from my best friend telling me "I just read the article YOU WROTE about anorexia..." and it made me really mad! Am I right to be mad at my mother for this? I want to ask her to send an e-mail to all the people she sent the article to to explain that I only helped with the form, not with the content of the article. Would that be right to do? I mean it really drives me mad!

PS: I live in Tanzania, but I'm Belgian and my family and friends live in Belgium, which is why we e-mail each other... Just in case you found that weird... But I know that she also sent that article to common friends we have here, and the problem is that because I live in such a small town, there are so many rumours about everyone (like I heard a while ago that I was refusing to eat and that I wouldn't eat many days in a row, I was really surprised to learn such things about myself!) and that's one of the reasons why I am so mad, because it is already quite hard to deal with such rumours, I didn't need an article to fuel them... Anyways, I need to clam down, I just got the e-mail and I am so mad I can't even read it!
