spiritual attacks..?

it seems.. when i'm about to be leading worship for Sunday services, something has to happen. so many times. falling sick, emotional trauma, last minute things that arise that may affect worship prac or stuff.. and it has to happen during the few days when i'm about to lead worship. man.. this is.. very mentally exhausting.. are these attacks from the evil one or what? haiz...

i'm really trying to do my best for You Lord.. i just want to believe that every bad thing will come to pass, that You will set things straight again.. i just hope to do what i can, and leave the rest to You. but i'm struggling Lord.. my mind is weak... i'm unable to ignore the emotions or feelings i have.. please heal me Lord. as much as i try to put the past behind, the pain is still lingering, the wounds are still open.. fill me with Your love again Lord. change the way i think, to think of You only. help me Father...
