Personally I've tried many medications for both anxiety and depression over the years. Prozac, welbutrin, lexapro, klonopin, xanax, marijuana. I was desperate for relief, but I've found in my research that medications for my particular source of anxiety (PTSD) are generally ineffective or may cause more problems. They'd provide temporary relief but I'd eventually backslide, as I wasn't dealing with the core issue causing the anxiety. I wouldn't consider myself depressed anymore, and my anxiety about things like people has definitely gone down, as I addressed why I had that anxiety in the first place. But I also know people who have lingering anxiety that is more of a body thing, or a part of their physiology. (From what I've seen.) It just depends.

Trigger warnings are ultimately ineffective. Triggers are personal, for one, and a certain phrase or scent can trigger someone. That's impossible to really avoid unless you know that person's individual composition. Secondly, avoiding what hurts you emotionally is never really going to be the solution.
