Trying to don't not forget what I've learned

It's been 2 weeks since I have finished my intensive English course, and I need to remember everything that my teacher taught to me. But it's too difficult because there's nobody close to me who speaks English.
The My main reason for studying English is only for fun pleasure... It could be difficult to understand because it takes me a lot if5 of time and I don't have too much time, but English for me is like a hobby even like a drug... The more I study English the more I want to learn more.
I've visited New York two times and I really love it... Because I can find native speakers everywhere and I can listen to different people with different kinds of pronunciation accents... And that makes me happy.

You use ellipses ('...') a little too much. And when you use them you need to remember that they act as a period, and end the sentence, so the first letter of the next sentence needs to be capitolized. But your English is good for a learner. Keep it up!
