Yes, I've experienced that exact same thing. When I supposedly got over my ED, I felt happy again, like I was someone important, that my life mattered. Then suddenly, it was completely washed away in a matter of minutes. After all the hard work and tears that went into overcoming the giant, was all thrown to waste. But I think you've already hurdled your first obstacle, you've admitted your problems reoccurance and have openly discussed it. Altho its just thru this blog, it's more than just keeping it inside. Slowly but surely, you got over it once, You can do it again. Good luck with it all! I know you can make it thru!
