It is not weird at all to wake up your parents when you're scared as a teenager. Feeling scared or anxious is a natural human emotion, and seeking comfort and support from loved ones is a common and healthy response, regardless of your age.
Parents are there to care for and protect their children, no matter how old they are. They understand that teenagers can still experience fear and vulnerability. Waking them up when you're scared shows that you trust and feel safe with them, which is a positive sign of a healthy parent-child relationship.
It's important to communicate your feelings openly with your parents. They will likely be understanding and comforting, offering reassurance and help to address the cause of your fear. Remember that everyone experiences fear at some point in their lives, and seeking support from your parents can be a great way to cope with it.
