Zsalynn Whitworth thought her life would greatly improve after undergoing gastric-bypass surgery, but the mother-of-one reveals she's still struggling with deep-seated issues.

In a follow-up to her My 600-lb Life episode, airing tonight on TLC, Zsalynn explains what's happened since she shed 300 pounds off her more than 600-pound frame. The biggest change is her divorce from husband Gareth, forcing her to share custody of their daughter Hannah.

"Being alone a lot has been a bit of an adjustment for me, so I've struggled with being depressed when I don't see Hannah for a while," she admits. "And being alone has made it even harder for me to deal with my cravings."

Given that food was her "coping mechanism," Zsalynn says it's been difficult to resist her old urges. "I know I should be loving life and loving everything that I've done to change myself, but I'm still insecure," she shares.

Something that should help bring back her confidence: getting rid of the excess skin left over from her weight loss.

Keep up the good work, girl!
