seriously i think everyone here probably suffers from a lot of negative self talk because of how we were treated growing up it sucks my therapist helped me out with this earlier this year and ill pass on some general advice   practice meditation it is hard especially with adhd try to carve out 10 minutes every day calmcom used to have 7 days free beginners  but meditation is all about calming the mind as you get better at meditating you can take those techniques into your day to day life now whenever im working on something and i start to be hard on myself i take a few deep breaths to calm my mind and kind of do a soft reset   and just practice forgiving yourself sometimes i even say it out loud its ok its not your fault just move forward
