Hello! So, I think that you don't necessarily need to talk to her about it now, unless she brings it up. If you're not comfortable sharing it with her, then don't. This is a very personal matter, extremely difficult to bring up and reach out about and if sharing it with someone you feel is judgemental then its not worth it.

However, if she does know and brings it up. NO matter what happens, if she handles it poorly.. remember that you have a wonderful group of people here to chat to and open up to.. with no judgment.

In relation to your purging getting really bad I know how hard that gets, I am currently in treatment myself. Never tell yourself however that you don;t need treatment or help because you say you're "overweight" and "don't really have an eating disorder anymore". Honestly, if you're still feeling the anxiety after eating and just generally feeling so terrible, a little help really does help.

I hope this message finds you a little better off, would love to hear how you're holding up.

Be kind to yourself
