You can talk about mental health/illness to raise awareness for others. You can talk about it to be understood. Everyone wants to be understood sometimes, and if there's a thing to know about mental health, it's that people don't understand, and you may not understand yourself. If everyone got it completely on all sides, it wouldn't be an issue. If you fully understood your condition, you'd fix the parts that are severe problems. It's just puzzles, in the end. Don't let people convince you otherwise. Puzzles.
