Despite actively participating on variety shows since his discharge from the army, Tony An seems to be showing signs of depression once again. The singer had previously confessed he suffered from depression on MBC's "Golden Fishery". Although he asserted that he conquered his depression by enlisting in the army, fans have been expressing their concern over his recent Twitter posts. On December 6th, Tony An posted up a series of tweets, stating: "For the past month, I haven't been able to sleep for longer than two hours... Continued nightmares... All I want is to be able to sleep comfortably." "As a foolish child suffering from a guilty conscience every day... As a foolish leader... I want to ask for forgiveness... I'm sorry, everyone..." "I would like to express my admiration for those that are living on in a desperate and painful battle against themselves." Fans began tweeting messages of support, stating, "Whatever you do, we love you for who you are. Please don't forget that" and "CEO Tony, remember that there are many people that wish for your happiness and hope to have those nightmares in your stead." Source + Photos: MT News
