Hi Ernesto, I can relate to feeling like a "new born" when trying to speak in Spanish and it sucks, but it's all part of the process. 

Jajaja cavemen, thank's to all of you folks, I'm gonna keep practicing and enjoy the process.

You should embrace the discomfort. Accept it as part of the learning process and have fun with it. 

I like to make fun of myself when talking to partners. I introduce myself and explain that I might talk like a cavemen or something like that. 

I have to agree with Gerald. Growing pains are part of the process, but they let you know that you are growing!
