No name symptom

I’m about to turn 19, but ever since I was about 15 i have gotten episodes of what is best explained to be short term memory loss. It happens randomly so I can’t give a specific trigger. The most I noticed is that it’ll happen after sometime after an event that catches me off guard happens. I don’t do any drugs and I’m not on any medication other than birth control. I’m diagnosed with anxiety and depression and have stopped going to counseling because of money issues. I don’t really know how to explain what an episode is like other than after i post this, I probably will completely forget I posted it within the next five mins. I remember basics like my name, age, where I live, but I can’t determine whats reality and what are just my thoughts. I get racing thoughts and if i try to remember what they were i feel like I’m making up a story. It’s very hard to explain but it’s scary and concerning. My close friends, boyfriend, and parents all know about this but it’s very frustrating and scary to forget about things within minutes of it happening. Has this happened to anyone or has anything similar happened?
