Ah good on you! You seem like a lovely person. Some absolutely do tell you a story to get a fix, and it is tricky. I visit Berlin often for work, and the sheer number of homeless people I have met and chatted to who seem to have become homeless due to a lack of mental health support is extremely sad. I suspect it will only get worse. I was lucky to be homeless in London respectfully weather wise, I can't imagine being homeless in Berlin as it is so cold.

This isn't for you as you do plenty but incase others read this, but if you happen to ever see a thick coat in a charity shop, second hand store, or thrift store (whatever you call it) and it is quite cheap, do buy it as there are many charities that take them to give to homeless people.
