Jana Kramer feels "embarrassed" by the end of her marriage to Mike Caussin.

The 37-year-old star filed for divorce from her husband of six years last month amid reports that Mike had cheated on her again but revealed that she feels a sense of shame that she has been unable to save the relationship for the sake of the couple's children, Jolie, five and Jace, two, even though her therapist advised her to leave.

Speaking during the latest episode of her 'Whine Down' podcast, Jana said: "I went to my therapist a few weeks ago like, 'Fine, I'll just live this life. It's fine.

"I didn't want to break up my family. My whole thing was, like, I didn't want this for the kids. I stayed for my kids even when other things happened but my therapist was like, 'You don't want to live this life where it's taking your light away.'"

The 'One Tree Hill' star continued: "I didn't want this at the end of the day. Where I'm at is – I'm embarrassed.

"I'm embarrassed that this is how it ended, and I also think that I've let people down. We've come on here and we've fought, and we fought for it. The words that were spoken, they were honest from me, is what I'll say."

Jana has tried to isolate herself from the world in the wake of the split and finds it hard just to get out of bed.

She explained: "When I grieve, I isolate. I don't respond to my people and I just stay in my bed.

"I had a friend come over the other day and she's just like, 'You have to get out of bed...' I don't know how to sometimes... The morning and the night are the hardest because I wake up and it's like that scene in 'Sex and the City' where she's like, 'Was it a dream?'

"It's so hard when I have all these feelings and emotions and then I have to be a mom on top of it. The first week I counted down to nap time 'cause I can go in my room and just shut the door and cry, just cry and then button it back up."
