Maybe you can spend time in the common areas of your residence; ask your room mate to join you, and you can both develop your English skills?
I have several family members who have English as a second language, and it was nerve-wracking for them when they first moved here. I also have family members who went on student exchanges and learned to speak second languages. It takes time, for certain, but you will do it! Reach out for support. I came upon this when I was browsing through the McMaster web site:

If you find it hard to understand your room mate, could you ask her/him to speak more slowly? She/he might also like it if you slowed down, too. My relatives and I
still need to ask each other to slow down sometimes
. Being open and honest is so important.
