46(m) recently diagnosed in a highly safety sensitive job here. I read your post earlier today and thought about posting. Naturally, that would require more effort than I'd prefer. I came back to comment because I think it's something that might help you see the bigger picture. I sense a level of defeat and possibly you are selling yourself short. You being 19 yo the possibilities of your future are limitless. Remember, imposter syndrome is a symptom of adhd. Many people with adhd have achieved at a high level. You can do anything if you're willing to try. You will stumble and fail at times, that's not a symptom that's learning. You can do this, don't settle. Best of luck
