As someone who was diagnosed with ADHD in my 40s, it was a great relief and surprise at how effective stimulants work. I have struggled my entire life, and have burned myself out multiple times trying to maintain a balance in my life. There's a huge mental burden every day. Trying to remember what you need to do, remember the best strategies to stay on track, spiking anxiety, feelings of guilt and shame, which can spiral into depression.
These sorts of judgement statements, dismissive words from family or friends, and indifference from the public over mental health has kept many people from seeking treatment for a very wide range of issues.
We need more empathy towards the fact that mental health IS health. We need more insurance support for these issues (because it's expensive!). Furthermore, we need more empathy and support towards those that do get addicted to ANYTHING. Addiction is not limited to drugs.
Starting with the assumption that people are drug abusers is damaging, and is entirely faulty.
