You have to find it yourself. And be positive about yourself always:)
Introspect
You should ask yourself
Allah ki ibadat
Everyone is here for a reason you will find out your purpose soon
Three different questions
Well these are very basic questions and the answers ain't that fancy like you're expecting it to be.
Meaning of life is to find righteousness and the one who set standards for that righteousness and follow those standards until you meet your end while keep all other things in the continuum.
You're here because of a pact which was made with your souls and it is called Tar ul Alast, where you acknowledged the creator and He has sent you to the world with all things in it(halal, haram, leisures etc) as a test to see how well are you maintaining that pact.
Your purpose is to find truth, be submissive to it, be helpful and a kind human and die as one who believed and acted on the truth.
Pretty simple right?
That’s for you to sort out!
