When your thoughts overwhelmed you,do words fail you?

I am always overwhelmed with my thoughts that is why I find it hard to put them on words, I mean verbally, because I can also write them efficiently. This is my dilemma that I face right now, and I need to get over with it as soon as possible.. waahhhh!

When my thoughts overwhelmed me then I fail to gather words to say something I want to talk about and then only I find myself incapable against life being much more complicated and dominate on someone. But I am okay after I can voice out my thoughts.

I think my thoughts probably overwhelm me more. I sometimes get that many thoughts and ideas in my mind I can't write them all down quick enough, and I end up forgetting them sometimes! I also get times when I have this really good phrase in my mind but when I come to write it down one of the words will just blank straight out of my head. Not sure if anyone else gets that? I can be sat there for quite a few minutes before the right word comes back to me. Luckily the right word has always come back to me so far:) I write pretty fast so most of the time I am fine, but if I slow down for one second then I hit problems.
