Mr. Sayeed had provided you links to improve your COMMUNICATION SKILLS - ORAL / WRITTEN.
From your post, i conclude that your written communication skill is good. You haven't made GRAMMATICAL MISTAKES. Its better you stop using SMS LANGUAGE and start reading NEWS PAPERS, BOOKS, WATCH SOME GOOD PLAY and reproduce SUMMARY on your own.
Follow this methodology LSRW.

Everything you do should be TIME BOUND.

Try this techniques to improve your reading, speaking, listening and pronounciation skills in english.
Read English newspapers, magazines, articles aloud (not so loud ok, just audible enough to your own ears)
Play Crosswords from newspapers or other source etc.
Avoid using - chatting, sms, texting languages or abbreviations, in writing or speech.
Start word card technique, i.e. choose 5 - 10 words of english, and learn to read, write, pronounce and meaning of the word before you go to sleep and try recall them when you wake up in the morning, if you cant recall refer to the word card, maintain this word cards, over the time, you can count your vocabulary. choose nouns, verbs, adjectives etc to learn.
Speak with your siblings, colleagues, friends, strangers in English as much as possible. take feedbacks, corrections, criticism positively and sportingly with a big smile.
Watch quality english movies to improve your speaking and listening skills, I recommend - Ice Age, Shrek, King's Speech, Pursuit of Happiness there are many more, but I cant list them down here all else you will be busy watching movies only :-D
Read a paragraph or short stories (KG books, short story books etc) and record your speech, and listen to it. note your gaps, mistakes, errors and work on it. catch the pattern of your mistakes.
Listen to Audio Books (Not excessively).
Stay focused and passionate about learning, at the same time, take it as fun activity and enjoy it.
Dont restrict, pressurise or stress yourself with time limits, learning is a continous process. bit by bit, word by word you will grow and learn.
Wish you all the best.
