just because you can't see it doesn't make it any less real

Why is telling someone you have been diagnosed with depression/anxiety an opening for people to say things like; “You just need to get out more”, “Oh I get sad sometimes as well. You’ll get over it in a day or two”.

No, you don’t understand. I have days that are so hopeless that I think of ways to make it stop/end myself. I’m not just “sad”. So stop saying it!
