Ahh i see, you need to be calm when speaking in order for your brain to process the words fully since you aren't fluent and also, read a lot of books and actively(meaning you jot all new words and look up their meanings) listen/watch English talks, news, videos and films. I hope that answers your question. If you'd like to practice speaking, I'd be happy to help you develop a study plan. Feel free to look at my teaching profile and class offerings and send me a message if you think I can help you.

I learn vocabulary by doing hobbies in the language I am learning. For hobbies like sport and craft, it is okay if you don't know the language. You can copy others. And slowly you learn a lot of vocabulary and have fun at the same time! Michelle https://www.italki.com/michelle

Read more. Listen to things in English. I don't think there are any shortcuts.

just try to find a good topic that motivates you to speak and search new words related to that topic
