I was an addict from age 19 to age 41. It does feel like being a child learning to do things and interact with people for the first time. Figuring out who I am and where I belong is a process. Give yourself a break and give it some time.
I was so worried about being boring once I got clean. The truth is that I was incredibly boring when I was stoned all the time. My old party friends are boring. Fighting with my girlfriend about drugs and alcohol all the time was so boring. I can't imagine anything more boring than my old stagnant life getting wasted night after night doing the same old routine for twenty years.
