I think your problem is that you are trying to do EVERYTHING so fast you are missing points and not getting it all together.
First, before you go adding flash in you need to learn how to control Shutter Speed, Aperture and ISO and how they will have an effect on your photo. THEN you can add flash, but if you do it all at once it's more than confusing. Flash changes the rules.
Stop. Slow down. Take a week or a month or a year practicing with each element until you have a great mastery of it and completely understand.
Throwing in a little posing and how to find the good light at the same time won't hurt, but the in camera work is complicated when you are learning. Until you figure out each element it remains complicated and you won't get amazing results.
It feels like you are constantly throwing up any snap shot you take for CC. Not that anyone minds cc'ing them. That's not the problem. Stop just shooting in a quick, random whatever. That's for the snapshots and memory "mom" shots. To master and get the PORTRAIT shots-stop, slow down, plan, think. Pair it with whatever you are working on. If it is aperture then work with the depth of field and ambient light. THINK for a minute about exactly what you WANT to capture. What you envision that image to look like in your head if the best photographer ever were behind the camera. Then analyze what you want and turn it into what you need. Where do you need the light to fall? Where do you need to be? what should your settings be for the motion in the image? for the depth of field you WANT? Do you need some extra light? Use a reflector to put more light back on the face. A reflector can be as simple as a piece of white poster board, foam core craft board is awesome, a car window heat shield...
Stop scurrying around here and there, to and fro shooting everything you can shoot with little thought to the staging. You'll be amazed by what happens.
