The question wants to analyze your writing ability and get to know a personal moment in your life. In that case, I can't write your text, but I'll show you how to do it.
First, you should know that a simple sentence has only one clause and that clause is independent. An example of this is the sentence "I'm going to walk the dog."
A compound-complex sentence must have at least three clauses, where two are independent and one is dependent. An example of this is the sentence "I was reading and he was joking when it all came crashing down."
In this case, you should know that a dependent clause has no meaning by itself, while the independent clause has meaning alone.
Once you understand this, you can write the text at a time when you were very happy.
