What should I do?

I’ve had a lot of going on with life that have been hard to deal with. I can’t really talk to anyone about it because well, no one understands and no one cares to understand. So I decided to make a journal to put all my feelings down so I could have some sort of relief. I would write about my mother in law practically bullying me. She has pushed me around, told me many times she would beat my ass, when I got pregnant she tried to say that I was gonna follow the way she tells me to raise the baby or she’s taking it away, tons of things. I would write about my husband not sticking up for me, how he always puts her first, and wrote about everything. Well he found out about the journal and got pissed because I wouldn’t let him read it. He said i was “keeping secrets from him” and I just told him that book is just feelings I wrote down about everything everyday and that it would be in his best interest not to read it and that it was very personal. Right away he said “you better not be talking shit on my mom in there or we’re gonna have some fucking problems she has done a lot for you” (she used to do some shit for me but I have also done a lot for her and she just holds the shit she’s done for me over my head) and so I told him even if I did it’s non of his business. And then he got super pissed and still is bugging me to read the journal. Should I just burn the fucking thing and never write again? That was my only outlet..
