I think it's important for children and young adults to have someone that they are able to talk to, and there isn't enough help.
What will you be doing and when?
I walked Snowdon on 1 June, and then I walked around the Lake District!
About Flynn
I'm Flynn, and I'm nine years old.
My mum started walking for charity in lockdown and I wanted to start walking like her. I've done a few long walks around where we live and I walked the Chiltern Hills.
Snowdon was top on my list, and I had so much support.
I love my rugby! I play for the under nines at Welwyn and have been on the Saracens pitch recently and got to go in the players' lounge and meet them all. I also got to lift the cup at Twickenham two weeks ago.
I love history and the wars - it's so interesting to me!
Why is mental health important to you?
I think it's important to have someone to talk to.
My great nan died in lockdown and I have really struggled with losing her - I get very upset and it would be helpful to talk to someone but its very hard to get hold of them.
