Demi Lovato's boyfriend makes her feel ''so much better'' when she has an anxiety attack.

The 'Skyscraper' hitmaker admits she is often left feeling like she can't catch her breath and gets ''very shaky'' when she feels anxious but Wilmer Valderrama is always able to help her overcome the attacks.

She said: ''The first call I make is my boyfriend. He calms me down and makes me feel so much better.

''But having people who are professionals as well and not relying on just one person is another key to maintaining a healthy recovery. I talk to my therapist. I'm actually in AA, so I reach out to my sponsor. I talk to the people around me, like the people on my team. I vocalise a lot of what I need and they're very understanding. I'm very grateful for that.''

Demi - who has previously sought treatment for self-harm, an eating disorder and alcohol and drug addiction - also finds staying active and being creative good ways to combat anxiety.

In an interview with the Huffington Post, she said: ''Exercising is another way I deal with anxiety. Painting, and writing music and expressing myself through art are other ways that I can release emotions. Meditation is another one. Whatever it is, it's important to find what works for you.''
