The fact that Roberto is being openly(publicly) admitting to his anxiety will help in itself. I'm sure there's been discussion regarding how many pro athletes are successfully dealing with this issue, Grienke for one. Osuna seems like a tough mature kid and has been on his own for a while now, so hopefully he just hit a temporary wall, it happens to everyone who's been separated from loved ones. Anxiety is a very complex issue where it can just a "blip" or a lifetime battle, hopefully in Osuna's case it's just a "blip".
It also puts perspective on the issues that so many Vets must be dealing/dealt with in their lifetimes, especially the Vets that were in WW1,WW2 and Vietnam where there was a draft. If pro athletes with all the glory and the money can develop anxiety in their surroundings, just imagine what what can happen to 18-23 year old kids who are taken from their families and thrown into hell half way around the world.
