Kaley Cuoco is staying strong amid her divorce thanks to the support of her fans.

The Big Bang Theory actress opened up about her split from tennis player Ryan Sweeting for the first time Wednesday, posting an Instagram of a Winnie the Pooh illustration about gratitude.

“I’m feeling completely overwhelmed with the outpouring of kindness and support from the people that surround me and from those I have never even met,” she captioned the picture. “I want you to know, I read all your comments and your sweet words have touched me deeply. I’m incredibly grateful for all your love as I start this next chapter in my life.”

Cuoco, 29, and Sweeting, 28, announced their breakup exclusively to PEOPLE in September. Sweeting is seeking spousal support, PEOPLE confirmed this month.

The couple got engaged just three months after they began dating and tied the knot Dec. 31, 2013.
