Sharing Our Innermost Thoughts

So the thing is my parents are fighting and i cant share what i am going through with anyone i know. They have never fought like this before. The past few weeks has been the first time and i feel soo suffocated. I have no sibling with whom i can share what i feel.
I feel so sad all the time now because my mother is not talking to us. And she has been making issues unnecessarily. lShe has been finding pointless things to fight and ends up making a big issue out of it.
I just dont know what to do. I cry all the time when i’m alone
