First off, that's only a fraction of the PowerPoint, and she might have made those slides to not reveal personal info to the internet. Hell, this could just be a joke with dozens of empty slides below the visible ones. However, the person almost certainly still has trauma. I've met a ton of people who cope through comedy, and a lot of them would laugh at this meme.

More importantly, gatekeeping trauma is not ok. Someone having a more traumatic life than you does not invalidate your own trauma. You could have trauma from common experiences, like parents divorcing or the death of a loved one, and it can affect you in serious ways. Many people never seek the help they need for their trauma because they invalidate their experiences. Someone always has it worse, so if trauma is making it hard to live your best life, don't feel guilty about seeking help for it.
