It's OK to need help. Everyone needs help with language.
You can do many things on your own. You can read more in English. Look at the website for the British Broadcasting System. They have many articles for people learning English. Another interesting site is www.livemocha.com. I am using this site to learn German. You can use italki to chat with people, to practice thinking in English.
Keep a notebook or set of small cards. Write down in the notebook or on the cards the words you see in your reading that you did not know. Review those words when you have some time -- even 2-3 minutes helps.
To really learn English, however, you must take a course or follow a program. A good teacher will help you make the most progress. (That is what my students tell me, at least, and yes, I am an English teacher)
I hope this helps.
