I recommend that you should watch English dramas, especially those you are very fond of.
In my case, it was 'Dr. Quinn'. What I needed was DVD box of dozens of episodes from Dr. Quinn. In this world of so many Internet services available, you can easily order DVDs of whatever drama. I ordered a complete box of Dr. Quinn from Amazon, published in the US, and I also bought a region-free DVD plyer. It wasn't very expensive, I remember it was about 8000 yen.
I remember repeatedly watching the episodes I loved most. So I could even tell what the characters would do next and what they were going to say. I believe an acute interest in the content makes difference in efficiency of learning spoken language.

When I was in England, I used to follow some comedies and I was so interested in the story itself that I forgot about my limited ability to understand spoken English. So why don't you do that? You can not only become good at English but also you are likely to get good tips of advice for your life through watching a well-plotted drama.
