The night before he died he told his mum he was "the happiest he had ever been" and was making plans to bring forward his wedding.
Gina described Mark as "the life and soul of the party", and he was not just her son, but her best friend.
She added: "We were always together, he would do anything for me. He used to say, 'when you die mam, I won't be able to cope' and I said 'of course you will'."
An inquest will be held into Mark's sudden death.
Sudden arrhythmic death syndrome
While Mark's cause of death is still to be determined, one of the most common causes of sudden death is sudden arrhythmic death syndrome.
Sudden arrhythmic death syndrome is when someone dies suddenly and unexpectedly from a cardiac arrest, but the cause isn't clear.
A cardiac arrest is when a person's heart suddenly stops pumping blood around the body, stopping breathing, which starves your brain of oxygen.
An abnormal heart rhythm known as an arrhythmia can lead to a cardiac arrest if left untreated.
A heart arrhythmia may not cause any symptoms, but if symptoms do occur they may include:

If you feel like your heart is beating too fast or too slow, or it's skipping a beat, make an appointment for a health checkup.
