Is there any support websites or anything like that?

like not a hotline that would be on a phone bill, but something like anonymous to talk to someone? online as in like a chat room? that would be open right now and all the time? like an emotional support thing for problems when u have nobody else. there are a lot of regular teen ones on the net, but they are either abandoned by most users or only have younger teens or pre-teens. im an older teen , like 18.
