It’s amazing to see the British finally begin to talk about our feelings. But even as we mark this year’s Mental Health Awareness week, there’s still an elephant in the therapist’s waiting room: alcohol.

The physical health risks of drinking are well known. Less discussed are the mental health consequences. These are real and significant, and seem to be getting worse. For instance, the number of people admitted to hospital with alcohol-related behavioural disorders has risen in the last 10 years by 94% for people aged between 15 and 59, and by 150% for people over 60.

Alcohol played a key part in my own problems but it took me years to come out of denial about it.

I never drank in the morning or in parks, just in a British way, bingeing along with, well, everybody else. I didn’t question it because no one else seemed concerned.

Presenting to therapists over the years with anxiety, patterns of self-destructive compulsive behaviour, swinging between thinking I was the most important and the most worthless person on the planet, they barely asked how much I was tipping down my neck. And it was a lot.

The more I drank to medicate my low self-esteem, the worse my anxiety got and the more I drank to dull it. Years passed and I couldn’t see I was stuck right in the classic “cycle of addiction”.

Eventually a friend of mine who had gone into Overeaters Anonymous sheepishly suggested I might have a problem. I resented it hugely. I was successful with a good job. There was no problem.

Eventually, it was a work incident that woke me up. As editor of Attitude magazine, I believed it would be culturally significant to have Harry Potter on the cover of a gay magazine. When Daniel Radcliffe, who played Harry in the film franchise, agreed, the only gap in his schedule for a shoot was early on a Sunday morning, which was annoying. Saturday night was my favourite time to go out. But fine. I could do this.

I decided not to drink the day before. No wine at lunch, nor during the play I went to see, and then straight home. All went well. Just as I was about to go to bed, ready for the shoot the next day, curiosity got the better of me and I logged on to a dating site, just to check my messages.

The next thing I remember was waking up, empty cans everywhere, with a bunch of messages on my phone asking where I was. Daniel and his publicist couldn’t have been nicer when I arrived with my lame excuse, insisting I go home to bed and that the shoot would be OK, and he found time later in the week to do our interview. Disaster was averted but it was the wake-up call I needed.

Since finally giving up alcohol, I’ve learned many things. First, that addiction is everywhere. That it is not about the drinking (or whatever the substance is), but the feelings underneath. Usually there is some kind of childhood trauma that needs to be addressed. I’ve learned that it isn’t about when or where you drink but about whether you can easily stop once you’ve started. I’ve also learned that there is an astonishing lack of understanding about addiction in general, not just from the public but sometimes by professionals who, being human too, often have their own issues to deal with.

The positive news is that despite alcohol being a socially acceptable carnage-causing drug that is pushed on us from an early age, it too is beginning to be talked about less furtively. Brad Pitt spoke in an interview last week about his struggles, Colin Farrell recently spoke on Ellen about being 10 years sober. Daniel Radcliffe himself has spoken about his problem drinking.

Last year I did another interview, with Robbie Williams and singer John Grant talking about their life-saving experiences of recovery from alcohol, drugs and sex addiction – and this time, I wasn’t late for it. Studies continually show a link between alcohol abuse and violence, domestic abuse and suicide, so talking about it is not a luxury, it is a necessity.

The British drink too much. Alcohol must be next on the mental health agenda.
