Ashamed of my English

I've been thinking about why I don't use Skype to practice my English with other people.
I think that the main reason is that I feel ashamed of my English. When I have to speak, words don't come easy and I often don't know how to finish a sentence, then I have to think about another way to explain what I need to say and I feel more and more ashamed. In addition to that there are many words that I write but I don't know how to pronounce them (how they sound?), so I have to prove the sound [not sure what you mean here] and my partner doesn't understand me. It's very frustrating. And exhausting too!
But there is one more reason. I have had previous bad experiences. I met a man to practice my English and I was speaking to him, but he had no patience and he was mean and rude. He made me feel even more ashamed.
I have a pair of very nice language partners and we write to each other but I don't talk to them.
I should do it. I practice my listening, my writing and my reading. I should practice my speaking too.

But there is one more reason. I have had previous bad experiences previously. I met a man to practice my English and I was speaking to him, but he had no patience and he was stern and rude. He made me feel even more ashamed.

I think (that) the main reason is (that) I feel ashamed about my English (You don't need to have 'that' twice in the sentence. I think it would sound better if you just had one 'that.' You can choose which one to keep or remove.). When I have to speak, words don't come easily, and I often don't know how to finish a sentence. Then I have to think about another way to explain what I need to say and I feel more and even more ashamed. In addition to that, there are many words that I know how to write but I don't know how to pronounce them (how they sounds?), so I have to prove the sound (Not sure what you mean here. I believe you're trying to say you attempt to pronounce the word?) and my partner doesn't understand me. It's very frustrating. And exhausting too!
But there is one more reason. I have had previous bad experiences previously (I think it sounds better this way, but it's mostly a matter of style). I met a man to practice my English and I was speaking to him, but he had no patient and he was hard and rude // One way to correct this sentence: I met a man with whom I could practice my English, but when I was speaking with him, he had no patience, was hard on me, and was very rude. He made me feel even more ashamed.
I have a pair couple of very nice language partners and we write to each other, but I don't talk to them (over Skype).
I should do it. I practice my listening, (my) writing, and (my) reading. I should practice my speaking too.

Tranquila, Beatriz. Escribes bastante bien y estoy segura que hablas muy bien también. Sigue practicando :)

Your written English is excellent! I'm sure your spoken English will improve, too.
