Throwing an enderpearl into end city portal and i get stuck in. Bricks of the stairs i built

So me an my friend beat the enderdragon and we went to the portal for the end city and went in just fine. Made a path to the main island then i had the bright i dea to build stairs closer to the portal so we didnt have to noob tower. Upon doing this and leaving i went back in by my self to loot it and instantly got stuck in a brick i used for the stairs .Then after suffocating i fall into the darkness lol. Any ideas how to take them stairs out
