You just described my situation almost exactly. Huge life changer for me to get medication. My mood is so much better and my confidence in myself at work is better than ever. I can finally trust myself and my skills and push complex projects like never before because the depressive anxiety and constant stream og garbage noisy adhd thoughts isn't holding me back anymore. I track my mood on an app every single day from 0-6 and you can se on the graph exact what day i started the medication because it went from the average hovering around 3 to now hovering around 5 which is just such a good feeling. Best of luck to you and I'm happy to hear you found help as well.

Edit, the app i use to track my mood is called daylio and works pretty good. Giving me good insight on my own mental health.
