many thoughts, zero words

do you ever feel like you have so much to say about a topic? something that you wanna talk about so bad, you might burst and explode, but the moment you try to verbalize your thoughts, you are left speechless, without a single damn word on your mind? any blog-writers with an issue like that?

i dont know if its my autism or maybe because im just more of a visuals guy, but i just. i just know i have so many opinions and i cannot verbalize them properly. its so hard. writers, how do you cope with this issue?
