Welcome back to the Wefugees Community and thank you for reaching out to us again.
I assume you saw my colleague's answer in the thread you opened last year May? I am sorry to hear that you are still dealing with finding an apartment. Did you apply for a so-called "Wohnberechtigungsschein" as my colleague suggested? I tried to make some research on additional support options and found this website. It is listing counselling offices and other institutions which give advice to refugees searching a flat.
I hope it helps and please don't hesitate to give us an update on your situation or to get back to us with any further questions.
All the best,
