Amanda Bynes' erratic behavior over the past six months has been worrisome - but speaking directly to In Touch, the former actress says she's doing just fine and debunks rumors she's suffering from a sickness. "I do not have a mental illness!" she told In Touch when we reached her directly by phone on Sept. 19. Since March of this year, the 26-year-old has been charged with a DUI and two counts of hit-and-run. Earlier this week, her car was impounded after she was caught driving with a suspended license. However, according to Amanda, she believes these charges are bogus. "There is no story there," she said. "There is nothing to defend." She also mentioned she was putting acting on the back burner again and giving fashion a go. "I am moving to NYC to start a clothing line," she revealed to In Touch. Along with her many legal woes, the former child star has been seen acting oddly during recent outings in LA. "She was on the treadmill watching something on the TVs and was laughing loudly," an eyewitness at the Equinox gym in West Hollywood tells In Touch. "People were looking at her. It seemed like she just wanted attention. She even took a phone call while she was walking and was talking very loudly." "Last time I saw her here, it was around 11 p.m. and she seemed out of it — she always seems out of it actually," an eyewitness at Rite Aid in Calabasas, Calif., tells In Touch. "She was in here for ages, maybe 20 to 30 minutes, just wandering around. She looked confused and ended up buying a soda and some cosmetics then left." Shortly after starring in 2010's Easy A — her last film to date — alongside Emma Stone and Lisa Kudrow, Amanda first announced she was retiring from acting, but a month later, she "unretired."
