Hi and welcome to the forum. As you will hear over and over in these threads, every brain injury is different, so "shouldnt I be "better" now?" is dfficult to answer (I was off work and couldn't drive for 6 months with my TBI). I think your going for the neuro-psych evaluation is the right next step, they can evaluate for cognative deficits and other symptoms.
Glad you joined and best to you in your recovery journey.
