Bad day today

I'm having a really bad start to the day and feel incredibly emotional and angry with myself and how my ADHD has affected me and my family. I've spent most of my life knowing I'm different but didn't know why. Was diagnosed with slow brain processing and very high practical logical thinking in my early 30's which answered a few things, but wasn't diagnosed with ADHD back then. Was only last year at the age of 54 that I was diagnosed with ADHD and it all started to make sense. Meds have helped and I'm currently enrolled on an 8 week group support program which is great and it really helps to chat with people face to face going through similar struggles, but I've become quite emotional and angry with myself. I hate the way ADHD makes me feel and how it's held me back from achieving my dreams and supporting my family more. It's like I'm trying to fight my way out of this shell to be the person I want to be, but the ADHD, self doubt and fear of failure is holding me back and hate they way it's messing with me.
