Hey there!
Obsessive Compulsive Disorder is also known as OCD. It can make people unnaturally anxious that things have to be perfect, and they can get worried. For example, their papers on their desk must be perfectly organized, and someone with OCD might spend hours making sure this is the case.
A lot of times, people get therapists and go to a psychiatrist or behavioral therapy, to talk about it, or get medication. You can learn to live your life with OCD and control it through these types of things.
The most effective for Roberto will probably be medications like antidepressants. They can ease his mind, and let him sleep when he's stressed.
Hope this helps!
