I'm going to agree with all of this. If you want to go into a professional field that uses your writing skills-- and there are many-- get an internship, or look into certifications that will help you get an internship, or look into ways to specialize meaningfully within those fields (tech writing, etc), and get an internship afterwards, and really, at any cost, find yourself some actual professional experience.
A Ph.D is usually going to be a detriment in the professional world. A Master's might not even be looked at well; my profession (training) loves them, but it very much depends, and I have friends who left my MFA program having much better job success when they left their graduate degrees out of their resume.
I say this kindly: don't clog up the applicant pool in academia if this is your goal. If you need any advice on getting a corporate job with English skills, though, feel free to message me.
