If I die young,will I go to heaven or hell, young?if yes then why wait to get old?

Depends upon whether you have obeyed the terms of pardon.

The time and means of death isn't the issue.  The issue is, do you believe in the Lord Jesus Christ?  When a person dies, they will be in heaven or hell, and they can't get out of hell if that is where they go.  To go to heaven and not go to hell, believe in the Lord Jesus Christ, without adding any of your works.  Believe in the Lord Jesus Christ, who is God and who died on the cross and shed His blood to pay for all our sins, and who resurrected from the dead.  See Romans 4:5 and 1 Corinthians 15:3-4.

BORN AGAINS WILL RAPTURE ahead of Tribulation...we all sleep before those things happen....UNsaved will fail Judgment unless they get saved before that.

I think there is a reason God instilled us with such a strong survival instinct, don't you? You should trust God's plan for your life. If God's plan is for you to die young, then you will be resurrected to eternal glory because you put your faith in God and God put his faith in you. If you kill yourself, thinking it's going to speed up the process, then you didn't have faith in God. You took your fate in your own hands and that's the opposite of what God wants for us. That will lead to eternal death.  

Would you rather be young in hell or old in heaven.

True!  You should go ahead and die so you'll be young forever in Hell.
