Hey there! :D Thanks for commenting on Library Love! This is my answer to your question..
How long have I been writing for? Hmm... Well, I started to write my first book in 2012. It was just for fun, but after I finished it, and another few books, I realized that I wanted writing to become more than a hobby and get serious about it :)
And I've been writing ever since! :D
Hope that answers your question!
