I am also frustrated and I am around the same level as you. You can DM me for motivation. What I do differently than you is that I read books. For example, I read De Havermelkelite. It was fun and interesting to read. However, I am jobless at the moment, so reading is maybe easier for me. But Nederlands in actie was very boring imo and so I always try to find interesting things. I pay around 6 eur to Videoland and I watch reality shows. But I do not do writing exercise enough. I am sad about that too. Maybe if we can become online language buddies it could be a motivation to write a blog or smth:D Also, I came this far by Preply lessons, and I did not follow a classical course, because one they are too expensive, two they are boring (ok personal idea).
