Hi Navya!
Apart from making conversation with others in the English language, which will give you practice and help build your confidence, reading is a great way to expand your vocabulary. It also helps to gain exposure to different ways of forming sentences to convey ideas.
Pick up something simple, something within your reading level, and set a time to read a little bit every day -- before going to bed at night works for me. If a book is too hard to understand, pick up something simpler -- you'll know when you find something that works for you. Eventually, your reading level will go up, and you'll also start to understand the grammatical patterns of the language. You'll also learn new words and understand how to use them. Different writers have different styles, so you'll also see how other writers choose to get their message across.
You can also go a step further and do a little bit of writing yourself. You can maintain a journal in which you can document experiences from time to time or occasionally write about your day. It's always nice to go back and read what you wrote a while back.
Finally, always try to use the language in the conversation wherever possible. That will give you a chance to put what you learned to practice.
All the best!
