Adderall has a super well known side effect nicknamed 'Adderage' that effects a large percentage of ADHD peeps. While it's nearly always rage-storms? (Hence the nickname), those violent emotional swings can also easily be anxiety, fear, despair, etc. If you're getting emotion storms on Adderall? I'd switch meds. Correction. First I would adjust my dose up & down a bit to see if there's a better dose, and then I'd switch meds.
Most ADHD meds have a well known side effect that's particular to that individual med (Ritalin/Methylphenidate family can stomp on personality for a large %, desoxyn tends to kill creativity for a large %, etc.)... But only a % of people are going to get that side effect. For many? Adderall is their perfect med. No rage storms, period. For others? 1 or more of the meds in it their system just really, really, really doesn't like.
There are over 80 commonly Rx'd ADHD meds... So finding the "right" one? Is very much -in my experience- a matter of choosing your side effects. All of them will improve ADHD symptoms, it's what else they do, in your own unique brain chemistry, that really determines which med -at what dose- is right for you. Side effects aren't all bad. Some side effects (like the ability to fall asleep quickly, deeply, and dreamlessly? Or positive body image?) Would be worth it in and of themselves. Other side effects (dry mouth, for example) can be easily fixed and are no bother. But other side effects? Like rage, anxiety, loss of creativity, etc.? Are intolerable. And that's okay. Because you don't have to put up with intolerable side effects. Ever.
The way to know an ADHD med is "right" for you? You feel like yourself. Shiningly, gorgeously, yourself. Not high. Not flat affect. Not crushed by anxiety. Just you. :)
All that said?
PTSD is often misdiagnosed as ADHD, Bipolar Disorder, GAD, or MDD.
So, yep. It may not be ADHD symptoms, but PTSD symptoms, that you're dealing with.
Or, you could be like myself (and several others on this site) who are both ADHD + PTSD.
So if you're questioning your ADHD diagnosis? That's totally valid, and very worth exploring.
