2B-2C coarse hair. Almost waist length.

I've been following the cgm routine for over 2 years now. I love what it has done for my texture and overall hair health. However, I've always felt like my hair doesn't grow out as quickly as I'd like it to. This paranoia or whatever probably stems from the fact that my mom didn't "allow" me to even trim my hair as a teen because it'd take years to grow back.

I've now realised it just poor health, but honestly (I am ashamed), I haven't had a trim in over 4 years. One of the reasons is how difficult it is to find a hair stylist/dresser who specialises in curly hair, but also because I'm scared of such a drastic change.

I do have hella split ends (obviously) and desperately need a chop. How do I go about it? Any particular hair styles yall can recommend? Tips to maybe help with the hair growth post the hair cut?
