Thompson reflected in an Instagram posting on Saturday.
"Yesterday morning. Nov 20th. 5:55 am. It was my birthday and also my last day of playing Patrick Drake on GH after 10 years, "Thompson wrote. "It was a long, emotional, exhausting, thrilling at times overwhelming day, and I am so grateful for every one of those moments. Change can be exciting and scary all at once. Shake it up..see what comes out. Thank you for the Birthday wishes. Thank you for the well wishes. See you soon."
