which way is Tir na nOg?

my hair is falling out with every handfull i inch closer to the day i don't recognize my own face in the mirror i marvel at how the past ten years have passed like (the snap of my fingers) it seems a lifetime and it seems a blink things i've learned and places i've gone float inside my head faceless and nameless i have memory of the past and no hope for the future i don't know what i did wrong how i ended up where i am my life isn't bad but it's not what i expected life is sink or swim we must do for ourselves come hell or highwater.... but i never had swimming lessons
