Assalamu alikum
I want to say, please don't worry, because you don't need to, leave it with Allah, make du'a to Him, and Allah will answer your prayers. Insha'Allah.
I pray Allah showers mercy on your beloved father, and grants him a place in Jannah tul firdos. Remember Allah is with the one who is patient.
.."Whoever follows patience - success will follow him"..
Allah made you strong so you could face the challenges life brings, Allah blessed you with Islam, so when you are worried you can turn your direction towards qibla to pray.
.."Suffering is a gift - it is a hidden mercy" (Jalaluddin al-Rumi)..
I want to leave you with something, which i hope will help you. I write poetry in my spare time, and this one below should be a help to you insha'Allah.
Allah is there
When things are going wrong, stand up high and be strong.
When life throws you something unexpected, accept it, don’t reject it.
When you think no one is there, remember Allah does care.
When you feel as though you are going to fall, reach into your heart and hear the call.
When you are going the wrong way, reverse and turn to the way you should pray.
When you feel all alone, don’t feel as though you should groan.
When you feel like no one can understand, give them a chance and don’t let go of their hand.
When you assume no one loves you, refresh your mind and think things through.
When you can’t find success, don’t believe life is a mess.
When the ones you love see you are doing well, they will know that you don’t deserve to go to hell.
When you consider the world to be blind, you are in fact going out of your mind.
When you are doing the right thing, reach out and sing.
When no one can hear you, believe in yourself.
When you don’t believe in yourself, think about all those that believe in you.
In my du'as always.
