When I feel frustrated

I felt frustrated when I want to explain myself and I don’t find the words. Explain feelings is not easy, sometimes because it feels embarrassed, sometimes you don’t want to expose yourself to a public, or even because you don’t want suggestions. However, sometimes you want to do it, but you can’t, especially in another language. Sometimes I want to tell a person something that happen to me when I was I child, or even an event from the past days, and I can’t explain what I really want because the language’s limitations. I need more than ever improve my vocabulary, I feel it so poor. Also, I need to improve my reading too, sometimes the meaning of the word isn’t a problem, and the problem is how to say the word properly. This are things that frusta me: can’t explain myself and don’t know how to say a new word.
