If you have never stood on the shore and looked at the ocean, you don’t know what that feels like. If you have never flown on an airplane, you don’t know the sensation of take-off or ascension.
Mental illness = same thing.
Yes, it’s true. You cannot expect everyone around you to really understand what you are going through, but that doesn’t mean they can’t help and support you.
On the flip side of this, if you know someone struggling with a mental health issue, you don’t have to wait until you completely understand to be helpful and a source of support.
Just being there is half the battle.
