Does it work?

I've tried to post on here a lot, it helps keep me motivated. One thing I haven't read too much about is guys specifically effected by ED, or at least post that really focus on it. Lemme give some background before I pose the question.

Two years ago I gradually started going downhill with performance issues...although the PMO was at a low point. But that got progressively worse and as it did so did the ED (and I'm sure some of it had to do with performance anxiety also). Now, I'm single and have been on the nofap journey for a three months. I've had a few small relapse and am now on day three after a 'mega' week long, many multi day PMO sessions, relapse.

The ED has gotten to the point where I can't even get it going all the way during PMO. Even with my favorite things...it doesn't get up until I stimulate roughly and even then it's only half way.

I'm really worried that I've done some kind of irreversible damage. And I'm worried that I won't be able to tell when I'm ready to actually settle into another relationship and get intimate again. I know it's kind of a dumb question but I need some reassurance that the ED (and the lifelong DE for that matter) will get better. So am I wrong in thinking that things are hopeless? Right now it feels like that are...but if they aren't then how do I know when I can 'get back to it' with some confidence?
