<human>: My mom and sister always fought, since my sister was a teen, they have different opinions and interests and it must be because they have the same personality (both are really explosive and hot-tempered).

I'm afraid they are making my dad sick with worry, because like me, he always gets in the middle and I'm really afraid it's gonna be bad for his health, he is diabetic and if he gets really mad or worried his pressure drops.

I've tried FOR YEARS to stay in my lane and not mess with them or get in the middle, but sometimes the fights are so big that I feel the need to do something and try to fix it, I matured so quickly because of this, and I'm not really happy, I'm suffering because I see my mom and sister really sad and I can't really choose a side. 

Sometimes they are both wrong and sometimes only one of them is wrong, but I can't choose a side and I try to talk to the one who is wrong but then I get yelled at.
I've been thinking about therapy for both of them, but it will never happen, trust me, it will never happen.

I have been searching for posts like this, to see if someone has the same problem, I feel so alone. I really think their fights are affecting my social life and mental health, I don't know what to do to ignore them, if I ignore them I feel really sad to see them fight, I just want them to get along.

Can you give me the gist of the text in a nutshell?
<bot>: Mom and sister are always fighting and I can't really choose a side because they are both wrong, this is making me miserable and I have been diagnosed with anxiety/depression and it's been affecting my social life for years.
