I can only relate how I've felt. Maybe you can identify. Repentance is a process (total repentance, that is), but initially very radical, like a jumpstarting of the system, the minute I truly heard and believed Jesus Christ. Maybe the strongest impulse that kept me there was fear of God, but not limited to that. I went from being angry, running with gangs, rampant drug use, and needing the world in all kinds of ways to….apologizing to everyone I hurt and shutting myself off to anything but Christ. Over the years, I've peaked out a few times, trying to "pretend I was normal", but it doesn't work.. and I just felt even more stupid and sinful for trying. Maybe there's a way to integrate, but I don't know what it is. If you don't feel out of place in this world, something's probably wrong imho.
Jesus asked "Do you also want to leave?” Simon Peter answered him, “Master, to whom shall we go? You have the words of eternal life." - Mt 6:67
