The Germany made me very tired, trying to cope with it

I've been living in Germany for a little over two years by now. I still can't speak the language. I work as a software engineer and I can't take any "good" language classes because they all start within my working hours, and I couldn't convince my employer to start working a little bit later and compensate the missing hours in the evening. It looks like the management team can home office from Bali and start working at 1pm Berlin time, but I can't do it.

I tried attending the Volkshochschule in the evenings, and it was so bad quality language education, half of the class has dropped it off just after couple of days. Most of the remaining students somehow made it impossible to learn anything. Imagine 30 y/o CS Master's student asking the English translation of every new German word coming out of the teacher's mouth, somebody watching Tiktok videos out loud, almost zero respect shown to the female teacher and the opposite to the male teacher and so on... So I couldn't finish it either. Such a waste of time.

Also, I've developed a fear of coming out of public. I don't want to mess with any German on my daily life. Most of the people (yes, a big word, but yes "the most") I've encountered so far have this tendency to be "hostile opportunist". People seem to be living their lives just to scold others, and taking advantage of every little opportunity they get.

Finally, the looks of the people on the street. I don't walk around so much lately, and I've already accustomed to the weird eye-contact level of looks is a thing in Germany. I'm not sure if I'm just paranoid because of the recent far right political events, but it seems to me these looks are more uncomfortable than before. It used to be like a curiosity type of looks, and it's now more of "what are you still doing here" kind of annoying or "being annoyed by my presence" looks.

I am not really sure if that's always been like this for foreigners, worse or better. But I am sure it's not the way of life for my family. In Germany, the stress and comfort of daily life are experienced in the extremities. The more time I spend with/around other people, the more stressed I get and the more lonely I feel. It's unbearable in the long term.

I'm wondering how are things in Switzerland when compared to Germany. Since my family speaks German (except me, I can speak English/Italian, but I will learn German in near future), I can't force them to learn English so that we can relocate to some non-German speaking country. All I know it's more expensive than Germany, and I don't really care about it so much.
