Jello....the word is "fluently". Check the spelling again....I can help you more with the speaking skills. I will engage you in conversations.

My key pieces of advice are:
1. Don't be scared of making mistakes. This is natural in any language and whoever you are speaking to will understand. If you take time thinking in your head how to say it perfectly grammatically correctly, it will take a long time for the words to come out. If you just blurt out the first thing that comes into your head, 9 times out of 10 the other person will understand anyway. If you have a good grounding in grammer, you will likely realise afterwards how you should have said it. And then next time you need to say it you will remember.
2. The more you practice speaking, the easier it will be. Talk to yourself, aloud or in your head, in English as much as you can. Whenever you have the opportunity to practice with a real person, use it. There are many great teachers here in Italki who can help you with this if you would like.
3. If you can't remember a word, just guess, or use other words to describe it. You'll be surprised how much of the time you are right. 

It sounds like part of the 'problem' is simply being a bit shy (even in your native language), rather than being fully to do with the fact that this is a second language. If this is just your personality, there is nothing wrong with that. If you do not like this about yourself, you can try to change it (again the more you try to speak to people, put yourself out of your comfort zone, etc, the easier it will become - I promise!). But don't feel like you have to change this about yourself just because society expects you to. There is nothing wrong with being an introvert.
