Can extreme stress and depression cause temporary memory loss?

I've been very stressed lately and I have a few mental health issues that I'm not sure are related. Yesterday evening I awoke from a nap to a text message. I didn't remember the person, who happened to be one of my best friends. I started talking to him and he answered my questions. I had forgotten a lot about myself, also. With help from him, my father, and my boyfriend, I didn't freak out. They answered most of my persistent questions. I now feel a little lost, but I remember the essentials. This has happened twice before, both very stressful times in my life. Is that what brought this upon me?
