Think about a time when you felt you had no freedom. For example, when you're parents we're enrolling you in a class or a sport you hated and you felt like you had no choice in it. Or, a time when you felt las if you were trapped, like the whole world was moving ahead of you and you were just stuck in there, not be of able to do anything. Look at an animal in a cage and imagine what you would feel like if it was you in there.
And dude, just let the words flow... They're in there somewhere and they won't go out by force.
Once you've finished thinking about that moment that freedom was taken away from you, express how helpless or defeated you felt. Reflect your emotions. Use metaphors and personifications to get the reader in the mood. And finally, talk about what you would have given up in that moment if you could only have your freedom back...
Hope this helped :)
