If you are only 14 and think have had insomnia for a long time how do know what can to fix it?

It's unlikely that you've had insomnia for a long time if you're only 14. However, if you're experiencing difficulty sleeping, it's important to talk to a doctor or other healthcare provider to determine the cause and get appropriate treatment. Self-diagnosing and treating insomnia can be dangerous, so it's important to seek professional help if you're having trouble sleeping.

That being said, there are some general tips that may help improve sleep quality:

- Establish a regular sleep schedule and stick to it as much as possible, even on weekends. This will help regulate your body's natural sleep-wake cycle.

- Create a relaxing bedtime routine to help you wind down before bed. This could include taking a warm bath, reading a book, or listening to calming music.

- Make sure your bedroom is dark, quiet, and cool. These conditions are ideal for sleep.

- Avoid caffeine and alcohol before bed, as these substances can interfere with sleep.

- Get regular exercise, but avoid working out too close to bedtime. Exercise can help you fall asleep more easily, but it can also interfere with sleep if you do it too close to bedtime.

If you're still having trouble sleeping after following these tips, talk to a doctor or other healthcare provider. There may be an underlying medical condition that is causing your insomnia, and they can recommend the best course of treatment.
