"When I was 14 I felt like the whole world caved in on me. I was angry and wanted to make it go away and I thought alcohol would help. I would drink until I passed out and often cry myself to sleep. I didn't realise at the time I had a problem but looking back I stopped doing all the things that I used to love like playing soccer. A lot of drinking turned into a lot of drugs, it's all a bit of a blur for a couple of years until I had a panic attack and my friend got me some help. I didn't want help at first, it took time but I feel like I have more control now and I'm taking it one day at a time. I'm 19 now and I want to do things I love again.
