It's hard to maintain your English skills if you don't use them daily.

I think it is really hard to maintain one's English skills if they're not used daily.

I lived in Los Angeles for 5 years when I was a student, which was about 10 years ago.
But since I've moved back to Japan, I hadn't had any opportunities to use English in my daily life until the start of this year!
Because of that, I've forgotten a lot of my English, but I've been picking it up again recently.

I've been talking with English speakers on skype on a daily basis since the beginning of this year. I talk with people for about 25 mins each time. That's a good amount of time for me to practice. It's not too short but not too long.

Now, I feel more comfortable and confident when speaking English with other people because of my daily practice :)
I still have a hard time expressing myself sometimes, especially when I need to translate from Japanese to English, and also when I need to discuss certain topics that I don't think about in my daily life.
I hope that I can keep improving my English so that I can express myself as well as in Japanese!!

Great work! Keep up the practice and you'll get your old English skills back and get even better than you were before in no time!
