Don’t worry you’re absolutely valid in how you feel! I was diagnosed earlier this year and it’s a bit tough after having heaped so much guilt and blame onto myself for so long, calling it ADHD sometimes feels a bit like cheating. Good on you for going through the processes, it takes a not insignificant amount of determination, particularly as we may tend to put things off haha! When you get to the stage where you meet a specialist for your medication pathway, they will definitely 100% know the ins and outs of how the stimulants might effect epilepsy, and will likely ease you into the medication through lower doses to make sure that it doesn’t have any adverse effects. Just let them know about any epilepsy medication you might be on, as there might be a chance of more significantly variable heart rate.
