I have ADD. Though, by today's standards, I would probably be diagnosed with ADHD (even though I don't have the hyperactivity).
And while I still have a few symptoms of it from time to time (these things never fully go away), I have learned to manage it and be functional without the need for any medication. So if having ADD/ADHD is a spectrum, I am probably on the lighter side. I don't expect anyone else to live up to the level of self discipline I've had to exercise; everyone has their own journey in life. Still, I think there is something to be said about the strength of pure will power.
I also learned in recent years (might have been earlier this year) that ADD / ADHD is a type of neurodivergence. That was an interesting find. Again, I must be on the lighter side of the spectrum, because most people wouldn't even know I have it until I tell them.
Last of all, for many years in my youth leading up to my young adult years, I was secretly battling with depression. Against all odds, I did overcome it. I no longer have those feelings, but I don't want anyone to shrug it off as if it wasn't that serious, because it was. My depression at times tempted me to consider... "unaliving" myself. I am thankful to have overcome those feelings. I really don't want anyone to focus on this. In fact, I don't even want anyone to think of this when they think of me. But I have to talk about this openly. Because if I continue to hide it or act like it never happened, then I haven't truly healed or improved after all.
