Struggling to Get Diagnosed with ADHD and Autism

just an angry vent about adhd and autism and diagnosing bs so i’ve been trying to get diagnosed with adhd since 2020, and that in itself is a complicated process i know. i’ve been on three different adhd meds, and last year saw a neuropsychologist (for the second time) and they gave me this half ass “attention/concentration deficit” diagnosis. so not 100% adhd. but recently ive realized that i might be on the spectrum. i’ve been self diagnosed as autistic for a couple months now after doing lots and lots of research and it’s made me feel more comfortable with myself. but today, my sister (who’s 19) went into see a neuropsychologist and fucking got diagnosed with adhd and autism after a couple hours! like. wtf?? i don’t know. is this normal? wmaybe i’m just being stupid and dramatic. it’s just been so hard for me to actually be seen and get diagnosed and she can get an autism and adhd diagnosis in one maybe two sessions. it just doesn’t make sense to me. this isn’t me obviously WANTING either adhd or autism. it’s just something i have been genuinely dealing with and it would be nice to have some sort of validation through a diagnosis and it pisses me off how easy it can be for some people. if anyone has any personal experiences or reasons why this may be it would be greatly appreciated. and if anyone bothered reading through this whole thing, God bless you. i apologize for this long rant. i just needed to get it out.
