Tatum attributes his battles with depression to his use of medications for ADHD and learning disabilities. While he freely acknowledges that such drugs are certainly beneficial for some people, when he was on them, he said, "it made me a zombie…I would go through wild bouts of depression." if you are interested in alternative treatments for depression, ask your doctor about your options.

In 2012, singer and actress Demi Lovato revealed in an interview that she sought treatment after suffering bouts of major depression and an eating disorder, among other things. Psychological disorders are complex and often occur together. Treatment typically involves both medications and cognitive behavioral therapy ("talk" therapy).

Sometimes, people who have never experienced depression have a hard time relating to those who do. You can't just "snap" out of it, and it's more than just "having a bad day." Pete Wentz knows this all too well. The member of the band Fall Out Boy reports being "immobilized" by his depression and feeling frustrated with those around him who tried to relate but just couldn't until he started seeing a therapist. Wentz's biggest piece of advice for others is to know they are not alone.

In the fall of 2014, Amanda Bynes announced that she had been diagnosed with both major depression and bipolar disorder, two conditions that were likely responsible for her recent episodes of erratic behavior. Bynes said she was undergoing treatment, which included hospitalization. Recent reports indicate that she left the hospital in November, and no further reports have been released lately.

Pop star Katy Perry is another young celeb who has publicly revealed her battles with depression.

Television personality Kendra Wilkinson might have felt all alone when she began having symptoms of postpartum depression; however, 10 to 15 percent of women experience this condition. Symptoms can include strong feelings of helplessness, guilt, or anger and an inability to care for oneself or one's baby. Prompt treatment is vital, of course, and it needs to continue even after a woman starts to feel better to prevent a relapse.

Postpartum depression is not the same thing as what are commonly called "the baby blues," as actress Bryce Dallas Howard discovered after the birth of her child. "[My husband] would ask what he could do to help, but knowing there was nothing he could do, I screamed expletives at him." A woman can feel exhausted, exasperated, and angry when adjusting to life with a newborn, but these feelings disappear as time passes. If they don't, or if other symptoms develop, you need to consider a diagnosis of postpartum depression.

When Zach Braff was preparing for his role as Andrew Largeman in the move Golden State, playing a character who has depression wasn't a stretch for the actor. While it seems that more women suffer from depression than men, women are likely just more willing to recognize the problem for what it is and seek help. In fact, depression affects an estimated 17.1 million adults in the United States.

Mad Men star Jon Hamm is no stranger to chronic depression. Like others, he treated it with antidepressants and therapy. What he appreciated the most about therapy, Hamm says, is that "it gives you another perspective when you are so lost in your own spiral." Depression is due to a chemical imbalance in the brain, and antidepressants help restore that balance, something else Hamm acknowledges.
