Meh, that old hard shell is what got me into all this.
An important thing I had to go through wrt my own A was realizing that although it was a mistake, it was also an important life experience that gave me some things I needed to learn. Granted, that's the hard and less preferable way to learn those lessons, but in many cases the hard way is the only way a lesson can be learned. So while you certainly shouldn't glorify the A (i.e. that was true happiness even if it was wrong, blah blah), you also shouldn't turn it into some monster from your past that you hide from or a stick that you beat yourself up with constantly.
Anyway, that was something else I had to learn before I could begin to struggle my way out of depression ... which I am still doing.
