Performing qadha salaah

Q: I started praying five times a day. Now I realize that I lost almost 25 years of praying. So according to this I was praying all this month but not regularly so Ramadan regularly praying almost praying for other days as well morning. Was it as well so I feel almost 10 years has been done now remaining 15 years prayers out there so I calculated for 15 years. So I need to clear 5475 pending prayers it is just an approximately figure please suggest advise me on this one

Trust in Allah Ta'ala

Q: I am an engineer and jobless for 2 years since my graduation. I have given so many interviews and tests for job but had no luck. Now mostly I am in deep depression and I also don't have my mother as she is no more to whom I could share my feelings. I blame Allah for my destroyed life and I pray to Allah to give me death. I heard a Hadith about Allah loves the human beings 70 times a mother, which I truly & strongly believe is LIE or atleast in my case..!! Thats it, I don't want your opinion to trust in Allah, believe in Allah, something good will happen etc etc. Have a nice day.
