I was recently diagnosed with ADHD (at the age of 28). I had no idea until recently that all the things that frustrated me about myself were even symptoms of ADHD, because they are so rarely talked about

I wish there was a lot more advocating for ADHD so it was better understood. It seems far too common for people not to find out they have it until they are adults, especially for those of us with combined or inattentive types.
It's so nice knowing now and getting proper support! I started medication about 2 weeks ago and it really is helping.
If you are still looking for sensory toys, look up Fun and Function, I've helped my clients with other disabilities get sensory toys from there and their catalogue is quite impressive.
