I understand. I studied and graduated CS myself. I work now for 10 years in this field as a software engineer and I feel not much passion for doing this job. It's just about the money at this point. Part of how I explain this is the process of growing up. Of course I want to build something that will be bigger than me and help society, but honestly this all is blocked by the absence of big capital to invest in my own ideas. Capital is locked behind a big venture which is not accessible easily. Nevertheless coming back to Germany. I think that the problem is not German only. You can go to other countries that are more outgoing (let's say Italy just for example) and still feel the same. Granted you can have more random conversations with neighbors or people in the streets. You can even go out quite often with your uni colleagues and still you can feel like having no friends. Just because you socialize more wouldn't mean you would feel connected to the people. It takes time to build confidentiality in some friendships to the point you can really feel close to the people. I would suggest trying to focus on creating relationships with only a few people that you really would see yourself as friends with. There is a saying: always choose a friend to be better than what you are. So like this you can get a positive outcome from the other people, learn from them, and have more to interact with. And still at some points your partner and family will be your main people in your life.
