A lot of this is conjecture. The numbers are there, but much more research needs to be done. There's been a huge rise in eating disorders during the pandemic. I think the access issues that were just spoken about are going to turn out to be a really big part of that.
For example, kids with ADHD are more likely to commit suicide if they're not treated. In fact, specific treatment for their ADHD, not simply depression or anxiety, reduces the impulsivity and the likelihood of suicide.
I think the isolation that we all experienced through the pandemic must have played a role.
There are so many different theories, but further research into this area needs to be done. Certainly we need to address the access issue now, but more research and more targeted approaches are needed.
