This feeling is real, and it’s also temporary. You can hold both.

These sound like competing claims and they are not. What you are feeling right now is not exaggerated and does not need to be argued down. It is also not permanent, even though it is doing a convincing impression of permanence.

Try not deciding anything important while it is at its loudest. Give it the night and tell somebody. If it does not lift at all, that is a reason to tell an adult you trust rather than carry it alone.
