Yeah I wouldnt project too much into this. If you are anything like me, you are going to find that sobriety will take care of alot of the anxiety that you are experiencing. I still have some anxiety but it is situational and Im able to use alternative methods to cope with it.
Dont let anything or anyone keep you from going to the assessment. What will it hurt? If you find you need a different alternative, you can have the assessment transferred to another provider and wont have to do another one.
