I Feel Overwhelmed Sometimes

So much shit is happening right now and I can't process it at all. Everyone in my immediate family is struggling with something or another whether that be financial or what not, and now the relationship between my mum and my step dad is falling apart quickly. I had quite the alarming conversation with my step dad not even 10 minutes ago in which he seriously told me he was considering leaving my mother and even the country because he's had enough of providing for people who don't appreciate the work he puts in. And I can't deny that he's been a force for good in my life, my mums life and my brothers life. And now that's all soon just gonna end. I'm not sure how to feel about it. Obviously I'm loyal to my mum but I understand where he's coming from. But at the same time he can't expect someone to change when they're so set in their ways. I'm sat in my room in dead silence trying to make sense of everything and even come to terms with the fact that I may be left without a father figure once again
