getting into journalism early?

Hi, I'm interested in getting into journalism/news. It's always been something I've been fascinated by, and I'd love to make it my career one day. But I have a few problems.

I've dreamed of going to uni, but I have not attended secondary school, mainly for mental health. Meaning I'm behind in a lot of educational and social aspects, and I don't traditionally take GCSE. I'm not sure how badly this could affect me in the future

I write most days during my free time about big news topics or just things i find interesting. Just for fun / to practice, I don't know if this will be helpful in the future or if I'm confident enough in it to make my writing public.

in short, I'm asking for advice on what I should do to progress into journalism, especially since I'm in a tough spot regarding education, any replies are appreciated :)
