I'm really sorry to hear that you have such a bad time in the Netherlands.
I personally have the exact opposite feeling when it comes to my study-period in the Netherlands. I also study (EU) law there, now finishing my 5th year at Maastricht University.
In my opinion/experience, Dutch people are probably among the most sociable people in our EU. They have a big hands on mentality and are very approachable, always willing to help.
Dutch people are however exclusively focused on positive feelings and will easily ignore people who are less sociable or maybe a bit down/negative (or maybe just realistic). This is the only downside I found in their culture, which definitely makes them a bit superficial from time to time. Yet, your experience with Dutch people seems to be very different than mine, to say the least. I find this surprising.
Key to having a good time in the Netherlands is to show that you are 'always excited, about everything'. It doesn't mater whether you're up for it or not, you must always show that you are. That's how Dutch people are raised.
I of course don't know your location/where you study, and which cultural aspects you struggle with. For instance, I study in a very international environment (50 % of students are non-Dutch at my uni, yet I favour Dutch people over most other nationalities due to their positive mentality)
Hopefully things will improve for you!

With the softening of a law making it easier for international students to get work experience while they study, the Netherlands has become an even more attractive country to study law.
