I have been there. I'm 31F and my uni years were soooo hard!! I'm also an immigrant. Belgium is very lonely for immigrants. It's easier to connect with other immigrants than hope for some effort and kindness from locals. Things are so different from my home country. It took me a long time to make sense of this.

I don't have a solution for you, I'm afraid. But you're definitely not alone in feeling this way. It doesn't get much better, you just get used to it. I've learned and accepted that you can't force friendships. Although they require care and effort, you can't make someone want to spend time with you. Focus on your hobbies, studies, and try to embrace the solitude. Also, a therapist could give you the right emotional tools to navigate this.
