Stuck in dead end in blasted steps

In blasted steps, i found a hidden tunnel by hitting a fake wall. At the end of the tunnel was a beast shard item. However, it seems that i can only get back if i would have double jump. But can the gameplay be like this that it forces the player to suicide in the game. The last bench is so far away so that it annoys me because i just couldnt afford the bench in blasted steps.
