A mother-of-two from New Milton in Hampshire says she struggles to cope after being diagnosed with tinnitus.
Claire Eveleigh says the condition, which has no cure, has left her feeling scared and lonely.
I struggle to cope and accept that I have these noises in my head for the rest of my life. I have two young children who need me and I struggle to function like I did before I had tinnitus. It's very scary and lonely and there's no peace. You can't escape it, it's with you everywhere you go, all day long."
The constant noise can be as loud as a jet engine or a dentist's drill, according to the British Tinnitus Association.
