Anxiety affects more than eight million people in the UK, and it can affect anyone, at any time, and at any age.

More important to remember, though, is the fact that it can come in many different forms, too.

Claustrophobia, for example, is a form of anxiety disorder that plagues many of us on a daily basis – and this irrational fear of confined spaces can often prove to be completely disruptive to our everyday lives. Just setting foot into a lift, tunnel, revolving door, changing room, plane or public toilet can be enough to trigger a panic attack, so many claustrophobics try to avoid using the tube wherever possible, due to a fear of being underground.

Thankfully, Transport for London (TfL) has addressed this problem with an alternative map of the London Underground, specially designed to help those living with claustrophobia or anxiety.
