I'm so annoyed with myself. I'm trying to stop binging/purging and i've gone 6 days without doing which is a big thing for me because i do it up to 3 times a day usually it and i was so proud of myself and today i just gave in and binged like crazy and purged!! what should i do? should i just start again tommorow..i feel so low.
