What can I do to commit to prayer and not abandon it, when my suffering from sorcery prevents me from being diligent in it?

Satan is keen on misguiding the servant. It is Allah, Who created and provided sustenance, Who commanded prayer. So, do not respond to blessings with negligence towards His right. Your affliction with magic is not an excuse to abandon prayer; rather, perseverance in it is among the most important means of prevention and cure. The righteous preserved prayer and grieved over missing the opening takbir. Therefore, you must repent to Allah and commit to performing prayers on time, and make up the missed prayers since puberty if you know their number, or pray what you believe is sufficient to absolve your responsibility, and increase your supplication for forgiveness.
