[Always *]

I am glad to hear that since posting this, you have spoken to a friend and that this has proven to be helpful. I can't say for sure if you have an eating disorder, but what you have described is definitely inline with the kinds of behaviours and thinking that are found in ED's. Having support from us online (and others), as well as your friend is a great start, as is coming here and telling us that you think something is wrong with your habits. Admitting it is honestly one of the hardest parts in my experience.
If you're ready, there are many ways that you can begin to explore ways to be healthier, both mentally so that your thoughts around your body image and stuff like that won't affect you so negatively, and physically, such as eating and exercising in healthier manners. If you're interested, you can PM me and we can always talk about it more, I'd love to help
