I have attention deficit hyperactivity disorder and suffer from severe anxiety, which I am currently being treated for. I just started working in an ER and the constant organization as well as constant reassurance that I am doing well has helped me with my ADHD and my anxiety. In talking with my doctor(psychiatrist) about lowering my dose of Adderall (at my request) I got nervous and asked him if I could request a higher dose if I find myself going scattered brain. After a discussion he pointed out that my main problem is the fear that I will not perform well due to my deficits and he assured me that he has plenty of patients who work in the healthcare field, I'm not the only one, and with the right medications many, many, many of them are doing an incredible job.
Do not be afraid to find the answers. Seek treatment and continue doing the job you love!
By the way, a bit of irony, a new student in the ER said she cannot wait until she has the self confidence and assertiveness that I have!
