As long as I know my head's in the right place, my feet are on the ground, I think I'll be fine.
Dad was just an emotional wreck. He was drinking a lot of the time, he was smoking a lot of pot. And because he takes certain medications, the drinking was making him... you know, he wasn't even present, really.
For a while I was suicidal and I tried to kill myself. I think I should have died about four times.
I didn't get at first put into a rehab facility; I got put in a adolescent psychiatric unit for my detox.
I don't want to come off like the jealous brother who wasn't getting the attention, but it was like no one was really into me anyway. I wasn't really a priority.
I had my group of friends, you know, like my real group of friends, and then I had, like, party friends.
I have a tendency to really stuff things. I don't really express, you know? Like, express certain feelings and stuff.
I took a bottle of pills. I'd been in Europe and I had a lot of absinthe and I was just drinking and drinking, trying to, you know, just shut my body down.
I was hanging out with no one under 21. I thought that if I really wanted to fit in I had to... show them that I was in a way just as adult as they were, 'cause I could hold my own just as well as they could, if not better.
I was interning at a record label - OK, cool. I'm gonna do what my mom did, you know, work her way up in the music industry, the business side of things. I was comfortable with that. That was what I wanted to do. And then just suddenly I am thrown from that. It was super insane.
I'd have to say that muaythai is something special. It's really demanding and it's becoming popular all around the world.
I'd read things, like people criticizing me. But no one likes to read stuff about that, and probably the main thing that was getting to me was me mum's illness.
I'm totally grateful for the fans my family has and I have; they gave me a lot of support when I was in treatment. But it was just odd, you know? It's stressful. Just the whole fact of being someone in the public eye.
I've been drinking and using since I was 13.
If I have a problem, stuff's going through my head, I feel like using, I usually go and talk to my dad... I decided to get sober a lot younger than he did. He first tried to get sober when he was like 32, I believe.
It's been real weird. It wasn't how I expected my life to turn out. Especially, mainly pertaining to the show. It never crossed my mind that one day I'm gonna be big and famous and have my own TV show, you know?
Kelly has a rather bad habit of interrupting.
There's a lot of things that were going on. I'd run out of OxyContin, I was doing a lot of Dilaudid. Dilaudid is like a millimeter down from OxyContin. I was doing a lot of those, and life just got super stressful for me.
There's people outside our house; you get followed by photographers; you can't go out and have a cup of coffee with a friend without someone coming up to you.
Well, all I can say is, it's a day-by-day program, and so I'm very worried about relapsing, but I don't know. I don't want to use. I don't want to go back to that place because nothing good came of it. It was super dark; it's not nice.
Where I felt comfortable was being the one that everyone liked to party with. And it was kind of the way I could fit in.
