I was a bit late to join this thread so couldn't read all the comments but whatever i've read here is my opinion about your situation :
Psychosis (your psychlogical Analysis)
You are depressed and home sick. anything your brother says negatively or out of which one can extract a negative meaning hits your like a train. Your regret coming to UK and no job could ever satisfy you unless your inside is satisfied. You are worried for your parents yet the touchy aspect due to depression is making you think of all that financial effect and their illness.
Suggested Remedy
Start having a broader horizon of thoughts like think of people who don't have parents anymore, peole who struggling with life since they are handicapped, a person who plans to commit suicide as he doesn't have enough money to get his family out of starvation.
Now the religious aspect ; whatever you'll earn, eat, possess in this world has already been written in your name its just the means and resources you use can be different. When and where will you have your next meal already there in the book. Who takes care of your parents? How long they'll live? etc etc has already been decided
Just start praying to God and then have faith in Him and His doings. I fully agree to your plan of coming back to Pakistan
Lastly
I'm earning a lot more than what you used to earn back in Pakistan but I'm about to retire in a few years and my initial plan is get any job of any salary pkg may it be 3000 a month 'cause it will keep me busy and in circle but will keep looking for better opportunities as well.
While in UK commit yourself and have faith in God
