Centers for men's mental health support?

Hello berliners, I am new to the city and I am looking specifically for centers that specialize in men's mental health and address issues such as paternal alienation, psychological abuse, suicide prevention, discrimination in legal systems, employment discrimination, paternal fraud, etc.

I am also looking to join some activism and causes and I would appreciate if you could send any initiatives in relation to activism about this.

Thank you so much!
