Should I tell my mom I think I'm bulimic?

If you are at all worried about this then it is not in your head, so don’t worry about that. Anything you think and feel justifies being talked about, so even if this does not turn out to be major bulimia, it is still something which is an issue for you an not usual behaviour.

I would definitely advise telling your mom- she will appreciate it so much that you can go to her about this (a lot of people with eating disorders would blatently deny it and be secretive) and will be able to help you, whether herself or by getting you in touch with a professional who can help.

I wouldn’t necessarily go up to her and say ‘ I’m bulimic’, but instead ‘I don’t want to worry you or make this into a massive deal, but I wanted to talk to you as I have noticed recently that I have had a few issues with food and am worried about it as it has gotten to a level I think it bad, because I have purged once or twice recently’. Then you can hopefully have an open discussion about it and how you feel and decide what may help you.

It is so great you feel you can talk to your mom about this and that you are sensible enough to realise this is something that is not healthy behaviour. If you get help now then you could stop yourself becoming majorly bulimic, so do try and talk to your mom. If you can’t find the words to tell her face to face, then write her a letter. Good luck!
