Mental health?

Hi ladies!

Here I come again to ask stuff that I need reassurance on or whatever.

I’ve been living at my boyfriends house for two years now due to my parents divorce and my mother kicking me out without a logical explanation. Ever since I’ve come to the acceptance that I’ll most likely never be accepted back home again like she did the last time after I graduate, I’ve had moments where I forget what year it is and where I am and it usually happens when I’m by myself at the house. Never out in public or at work. Like I could be showering and once I open my eyes after scrubbing my face, my brain just goes “woah let’s take it back to 2016” and I’m just looking around confused like why am I here what’s going on this isn’t my bathroom. And once I realize that its not my happier time frame, I get really sad and just cry for a good five minutes.

Sorry if this is hard to read. I was just trying to gather my thoughts to the best of my ability. My bf says it happens because I’m so deep in thought but idk. What do you you guys think?
