Kaley Cuoco is ''incredibly grateful'' for the support she has received since splitting from Ryan Sweeting.

The 'Big Bang Theory' actress, who filed for divorce from the professional tennis player last month after 21 months of marriage, has thanked her family, friends and fans for helping her to prepare for the ''next chapter'' of her life.

The 29-year-old star broke her silence on the split on Instagram, writing: ''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.

''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.''

Ryan, 28, recently filed court documents requesting spousal support from Kaley, who earns $1 million per episode, as per their pre-nuptial agreement.

The blonde beauty reportedly ended their romance because the athlete was allegedly refused to seek help for his ''dependency'' on a prescribed drug.

A source said previously: ''She supported him but she said he couldn't make the commitment to get sober.''
