I'm a non-native English speaker, however, I'm very proficient in reading, writing, and listening. But when it comes to speaking my accent and inability to start to "speak" just destroy everything. When I want to start a conversation with someone or to react to a sudden event I start to mumble, stutter or the words just don't. come out of my mouth at all. However, once engaged in a conversation I feel pretty comfortable. I don't know how to solve this problem. I've tried to work on my accent and pronunciation to feel more confident, but it is not helping.
