Out of interest when did you first decide* to become a Muslim?
*Decide meaning making a free choice with all available information about other options available and having no fear of negative consequences like being ostracised from family, friends, community, religious sanction (death).
If only it was that simple to undo a lifetime of indoctrination. Risking being ostracised from family, friends and your community plus of course the minor matter of the apostate death penalty sanction all helps to keep the 'faithful' in line.
