Edited Title: Welcome change; do not fear it.
Tore up a plastic lid into little pieces... would catch myself doing it so I'd stop... only to find myself suddenly tearing them up again. Now the nail beneath my thumb hurts.
Went to shower, took off my clothes, and found this mutated bug that looked like a small spider with wings walking across my chest. Typically, this would freak me out... but this time I just thought,"How the heck did it get there," then flicked it off me... turned on the water... and watched it go down the drain.
The most important thing is keeping a strong, stable mind... with that, you are mentally invincible.
