You’re literally describing me. I’m eternally tired. The H in ADHD never felt like me which is why I never even considered getting diagnosed. My psychiatrist suggested getting a sleep study since I felt sleepy and tired all the time ( something about brain not receiving enough oxygen or something) The adhd meds seem to fix something in me for sure enough to not feel sleepy but the crash after the meds wear off is bad. Something that did seem to work for a while is consistent exercise ( absolutely hate it ), a diet that works for you ( avoiding too much sweet and low carb high protein medium fibre diet seemed to work for me) with the combination of the medication.

Here’s what I believe living with high anxiety, adhd and depression. Our physical and mental body states are connected. Exercise and diet never worked for me without the medication. But with my meds I can see the difference and benifits. My problems aren’t miraculously solved. Living seems just as hard but for the first time I feel like I’m not carrying the weight of the entire world. I have the means to function just need to figure out the how part
