Help me get my ADHD diagnosis

Heyyy, everyone. I've had the suspicion for the longest time that I have ADHD, which has been backed up by multiple therapists I've seen - but because I don't have any legitimate diagnosis, I'm not able to get treatment or prescriptions. Just get a diagnosis, right? Well that's 1800 NZD, which is... approximately 1800 NZD I don't have qwq

If anyone has something they could comfortably donate, I would be super grateful - I don't want to put anyone in any risky situations, so please, don't donate if you're already struggling yourself. Thank you so much for reading and supporting me, whatever you do!
