Glenn – who performs under the stage name Rosborough – hopes others who are suffering in silence – like he did for years – will seek help, too.
Even though he has lived with the condition most of his life, things came to a head in recent times.
“I was in a car crash about a year and a half ago, that completely shook me, family members were getting ill, and just the pressures of being a dad, being a husband and life were starting to build up to the point where I was getting constantly dizzy every day,” he told BBC Radio Foyle’s North West Today programme.
“I was getting panic attacks, anxiety attacks and it was almost as if those anxiety attacks happened and they never switched off.
“I was just scared, afraid and panicked all day.”
That is when he decided he “could not live like this anymore”.
Opening up to his family was the first step, followed “the very next day” by an appointment with the doctor before he finally found a therapist.
He believes that is where his “healing journey” started.
