Wonderful article, Tobias. A lot of people suffer from anxiety and depression and more people need to be open and honest about it.
And you're right, there is a way through this. As someone who has had a lifetime of crushing anxiety and depression, I can say solutions certainly exist. Writing about it is a great start, but reaching out to a professional is essential. From personal experience, somebody trained in this can often do far more than the person suffering from it.
If you're German, make use of that healthcare system, bro. :)
