A British student can only wear clothes with zips due to a phobia of buttons.

Hannah Matthews, 21, has koumpounophobia, which means she panics in the presence of buttons and the prospect of touching them really freaks her out.

''My mum says I would freak out when it was time to get ready for school. I would scream, cry and as I got older I started to have panic attacks when faced with the prospect of touching them and getting ready.''

She said: ''Something about the texture and shape really freaks me out.

''My mum says I would freak out when it was time to get ready for school. I would scream, cry and as I got older I started to have panic attacks when faced with the prospect of touching them and getting ready.''

While Hannah has learnt to partly control her phobia, she still panics when the word ''button'' is mentioned in conversation.

She added: ''It really used to affect my chances in job interviews, but I know more about self-control techniques now, so if someone is wearing buttons I try really hard to control my reaction.

''It still makes me feel uncomfortable but I can now distract myself if it's just on someone's shirt, however if it starts coming towards me or the word is mentioned in conversation I still panic.''
