Khloe Kardashian has lost sleep ‘overthinking’ things ahead of return to

Is Khloe Kardashian having second thoughts about moving back to Cleveland with

Tristan Thompson and their daughter, True?

The new mom shared a pair of messages

on Instagram Stories this week that left some fans wondering if

she was struggling with the family’s

plan to leave Los Angeles ahead of the start of Tristan’s season with the Cleveland Cavaliers.

“RIP to all the hours of sleep I’ve lost to overthinking,”

she wrote on Tuesday, Oct. 2, according to People.

“You can go to the gym, drink your water, and take your vitamins,”

she said in a second post.

“But if you don’t deal with s— going on in your heart and head you’re still going to be unhealthy.”

According to People’s sources, Khloe and Tristan’s relationship, which suffered as a result of his

 cheating scandal, has become much stronger in recent months. “Khloé and Tristan are great.

Ever since they have both been in L.A. with True, they have really worked on relationship issues.

They had an amazing summer together and a gorgeous family vacation,” says one insider.

Now, however, Tristan is due back for his first games.

“They are all moving back to Cleveland, and it’s hard for Khloé.

She will really miss Kris [Jenner] and her sisters,” the source continues.

“It’s not going to be easy for her. But she is committed to keeping her family together.

And Tristan has shown that he is committed to Khloé, so Khloé will make it work.”

A second insider tells the magazine the plan has always been for Khloe,

Tristan and True to go back to Cleveland come fall.

“It’s their home,” says the source.

“But True will still spend plenty of time with her cousins and family in L.A. They’ll travel back and forth.”
