Facebook chat problem?? Please help?!?

[Drizzy]

Ok, so my chat will not go offline!! People see me online 24/7 even if I'm not on Facebook!!! What's going on? I tried disabling the chat on my laptop and my iPod touch, but people still see me online! Last night I got a message from my aunt saying "What I'm still doing up late at night??" and I told her my Facebook chat won't go offline! One of my friends said I'm always on Facebook and he laughed! How can I fix this? I tried contacting Facebook, but they didn't do anything! I also tried logging of on every device and still didn't work! This is annoying, because it just stays at a green dot, instead of a phone icon and it makes me look like I'm addicted to Facebook. It will not go offline even if I shut down my computer or my iPod! Please help??
This is not a joke question. I like did everything, I turned off the chat sidebar on my laptop, and my iPod touch. It even says on the sidebar"Turn on chat to see who's available"

Best guess, you are logged in on a device that you don't know about. Try changing your password just to make sure. If that doesn't work play around in settings and see if there is an "Always Online" setting.

deactivate your account and activate it again it might help but i'm not sure of it
