Oh Frosty write what you want to. It's all about how you feel and where you are in life. Not everything I do it all bubbles and fun, I have a darker side too and while most of that stuff is gone for reasons I really don't want to get into I went through it and for it all I came out a better artist. So follow your heart and write what you want. You are really good and I hope to be able to read more of your work!
