Try converting your thinking to English so that you don't have to struggle while framing sentences. This would help you avoid translation, which can be intimidating. Try to speak to yourself mentally in English about anything you do in daily life. For example, if you are preparing a cup of tea for yourself, try talking to yourself like: "I am preparing tea for myself. I have taken a pan and put some water in it. Now, I have switched on the stove," and so on. You can do this with almost everything you do in your daily life. This practice would be beneficial.
You can also do a mirror exercise - take any topic and speak about it in English in front of the mirror. Start with easy topics like "My family," "India," etc. Then, move on to more challenging topics. This exercise will increase your confidence and help you shape your thoughts effectively.
