Hello Angelika, 

Many Russians have the same problem as you, so you are not alone. There are extra sounds in English that don't exist in Russian, and the only way to learn them is to practice with a person who can speak English well. I think you need to use a phonemic chart, and practice some of the most common words, and then practice having a conversation. I promise you can learn to say English sounds easily, maybe in two or three sessions with a teacher you'll be pronouncing the sounds properly. Good luck. 

I understand...

I understand that I have a big problem. I scruple struggle to speak English. Pronunciation of some sounds confuses me. I think when I speak say something it's look sounds stupid. For example, I can't say "mouse" and "mouth". It's They are different words but I pronounce them evenly the same.
