Comparing yourself to others is an easy way to think negatively and possibly even descend into depression. It's important to accept who you are and what got you there and not think that your life would be so much better "if only things had been different". Things weren't different. You were given the genes you were given from parents who you didn't choose and countless other variables influenced you to become depressed and then recover at the time you did. No need to feel bad about it.

I don't mean for this to sound like a personal attack. I'm in a similar position to you and I've found it incredibly rewarding to realize that it is useless to worry about the past and what could have happened.
