Fired

Woah! What a damn day....
Our new shop is almost complete, carrying loads of hopes... I dont mean to show off or something but i've masterminded that shop, im the one who organised everything, i worked day and night for it. My dad just spent the money. I build the new shop. BUT guess what, today my dad tells me that he is selling the electronics shop, the biggest and most popular one, he continues saying that i must look for a job, im no longer required because Mani (my cousin) will handle the new shop while he'll handle the other grocery shop. I was like WHAT? He said i never listened to him so now its too late. He was very harsh. Man, i worked so hard this time, even successfuly repaired some phones, but my dad's reaction towards me has never changed, im still and always be a zero and loser in life...
I dunno what to do now but Allah knows that this is so unfair... I deserve the credit, screw the credit, i should be allowed to work and be part of the new shop because while building of that shop i always planed my future. But im fired.
