Brie Larson has opened up about her struggles with social anxiety and admits she wants to help others by sharing her own story.

The 30-year-old Captain America actress, who also explained how she is ''introvert'' and suffers with asthma, said that "telling my story" has helped her overcome many challenges in her life.

Speaking in her YouTube video, she said: ''For me, my baseline has been, I'm an introvert with asthma. Like, that's been my story for myself ... I'm introverted, I'm scared, I have social anxiety.

"And through, in particular, playing Captain Marvel, that like kind of wiped clean those titles I had for myself and made me go, 'Woah, I'm not really that anymore.' And so, from there I found that speaking out, telling my story, talking about things that I'm scared of, has just helped me so much.''

Larson said she wants to inspire and educate others with her YouTube channel and to talk about things that are "important and that matter".

''YouTube has been a place that I have learned so much. Whether it's been like, how to use my printer, or it's been watching like, how to be a considerate activist.

"This is like the place to talk about things that are important and that matter."

"It doesn't mean that there isn't also silly content, that there's ways for me to express myself personally. But, there will also be deep conversations, anti-racist rhetoric, inclusive content.

"So, with all that said, the following video is just me getting warmed up and feeling this out and getting to talk with a lot of really brilliant creators.''
