i need help expressing what i want to say in writing?

Don't worry about how to say it. Write down what you want to say -- every thought that you have. Then later go back and figure out how to say it correctly, or whether it's what you want to say at all.

Have no idea what you're talking about. Writing in a journal, writing an essay, writing an autobiography, writing a novel??????

Create an outline. That way you'll know what you want to cover in your writing, you'll stay in topic, and organized.

Best,

Alex
