Can you revise this into better English?

(Better grammar and make it short)

Don’t worry what other people think. They don't know what really happened and the difficulties you were going through. They're only basing their judgements on the facade and the opinions of others. Let them destroy your image in order to protect themselves. But please remember, my child, that I hear and see everything. I'll be here for you! - Hebrew 4

The grammar is ok and doesn't need improved.
You could shorten 'other people' to others and the word 'really' in really happened is redundant but personally I'd leave it in given the context.

Or

Sod them all, they know shit, I'm always here for you.

Sure, here's a revised version:
"Don't worry about what others think, as their judgements are based on a facade and other people's opinions. Let them destroy your image, as it protects them. But never doubt that I hear and see everything, and I always exist as a source of support and guidance for you."
