Sometimes you might get stuck in a cycle of thinking too much about things. It might be something you don't need to worry about, but you just can't help going over the same thing again and again.
It can make you feel stressed and confused and you might struggle to make decisions because you worry about what might go wrong.
Thinking about things and trying to solve problems is normal behaviour, but when you overthink it takes up a lot of your time and energy and makes you feel anxious and upset.
By young people, for young people
"Every time I step into a classroom I feel ugly and uncomfortable, trapped by eyes staring me down. It is an overwhelming pressure that makes me feel my heart and head pounding.
"These thoughts control my walk, talk, mood and concentration. I am not me anymore. Do I look too slumped or proper? What am I to them? I think if I could have any super power in the world I would want to be able to read minds so I can finally be at peace."
