Feeling of losing my memory?

So I have a panic disorder and recently I’ve just been feeling a lot worse. A few days ago I started having this feeling like I don’t know who I am and I don’t recognize my family. It’s very scary and I don’t know exactly why it’s happening but I’m worried it’s getting worse. I’m terrified of just suddenly not recognizing anything. I started taking new meds over a month ago and I just recently started another one under a week ago. I have a therapy session on Thursday but I’d really like some advice or similar stories now if anyone has any. Thank you
