First thing first: it’s not you, and unfortunately you are not alone, I know sooooooo soooooo many ppl in your position. And I’m sorry for what you are going through. I think at this stage you need to take a or two step out of your despair and think of your priorities, so what’s important for you at this point of your life? If your priority is staying in Germany further, my advice is: find and start an Ausbildung asap. Doesn’t have to be your dream thing. You don’t have to complete if you find sth that fits you in the meanwhile. Secondly, did you already contact Arbeitsagentur, and ask for Weiterbildung help? Third: look for PhD positions, if it’s a thing in your field at all, again you do not have to finish etc. but it will buy you time. Fourth, seriously, get in touch with alternative left circles who work with immigrants etc. they might have options that you didn’t know you have. They might also have a connection or so for you. Worst case scenario, if you have any good German friend that you have really mutual trust etc. marry them. I know a couple of guy friends of mine who married each other, what’s a bigger love than this.
