The mobs there are over 50, they are inside the circle, you only have a 3x3 space without mobs, no matter the width.
You do not have anything except what I mentioned.
You cannot change gamemode, that would be way too unfair. Also you are alone, anyway you would die before help arrives, as the mobs are creepers.
You have tons of raw iron but cannot use it because you got no furnace, and it is too valuable to lose
