I really like Thara's comment!  That is great advice!  Thank you so much.  I have this problem too.  I love learning other languages but I am always nervous to talk to strangers in a foreign language, I am scared they will think I sound like my pronunciation is bad or they will act like I don't think they can speak English and might feel insulted.  But people usually have been nice and usually always love to talk to me in their language.  But I had some other Americans make fun of my French before and I have been scared to speak it out of fear of being made fun of.

Thank you so much for your opinion. I think it really works!

When I was learning Russian, a guy made fun of my pronunciation. I felt humiliated and it's become my complex.

Then I thought, it's not my problem, at least I tried and making a  mistake actually takes you to another step in learning progress. In fact it's his problem that he couldn't accept the fact that I was learning his native language. He should have tried to understand and help.

so make mistakes, learn from them, don't be shy to ask people to repeat and say " I don't understand' ( If your sentence isn't understandable, try to change words or structures insteading of feeling embarrassed), ignore people who make you feel down and always be positive:)

I think to learn culture is the most important way. 

I feel embarrased but i don't give up .When you feel that your non-native language is good enough to be understood by native language i think you're who make the first obstacle against you :)

Expect the Little Not to feel despair . The greatest thing to find someone who don't tell you much that i can't get what you say . I Prefer to try to get what he want to say and let him to speak even he/she makes mistakes to make him feel confident .
