It is psychological, and there are things you can do. Firstly, after having a friend from the country you are wanting to visit with, I think you will realize that all you need to do is communicate your idea. If a word is missed here and there, you are still having a conversation with successful communication... Having that friend will make you start to realize that you are not being judged for having an accent from your homeland. It is only part of what makes you unique (which is a VALUED thing where I come from.) What you are dealing with is YOUR comfort level. Not so much others. This is what I suggest you consider.

You ignore it! It never goes away by itself. You just ignore it and talk. This is what separates the men from the boys.

Believe it or not, this is the single most common problem that people have for progressing with a language. You just have to (as Nike says!) do it, and most people will be pleased you are trying to speak their language. That way, you will gain confidence. There will be the occasional idiot that laughs at your attempts, but just ignore them!

Your written English is perfect. The first time I spoke a foreign language to native speakers, I was very nervous, but they realised I was trying and helped me. It became easier each time. Most 'ordinary' people are friendly and helpful, if they are not in a hurry, and often want to know about your country. Good luck!

you are better than others just try to give little more time ......&....stop worrying and thinking about others.....
