Is it weird or dangerous to give myself advice through an imaginary friend?

I'm a teenager, and I created a sort of imaginary friend to help me cope with stressful situations or if I'm worried or upset. She "gives me advice" and comforts me and tells me it'll be okay. I've given her a name (Solace) and created a personality for her that's like a comforting motherly figure. I know it's just my own advice and my own thoughts, but it's just that I'm thinking of them through a voice other than my own. I do this because I know I never really listen to my own advice, and I thought it would be better if it was through someone else who knew my thought process in and out, through this imaginary friend. Is this normal? Could it develop into a separate personality with time if I continue a mentality that she is her own person?
