Please help, I’m desperate..

I (25F) have SEVERE memory problems. I can’t remember anything and it’s starting to ruin my life. I can’t remember conversations, I can’t remember doing things, I can’t remember details. I think it seems to be my short term memory? It doesn’t matter if it’s been 2 minutes or 3 days.. I’m 5’4, 150lbs, no current medications, no current medical conditions, non-smoker (occasional vape socially).

Backstory: for example, my fiance and I talked on the phone at 7pm last night (7/03). During that phone call we discussed plans for the 4th of July (today). I wake up to a phone call from him asking where I’m at and I told him that I was sleeping. He got frustrated and said “you’re not coming?”… I didn’t know what he was talking about… he proceeded to explain to me that we talked about the plans, in detail, on the phone last night. However I have NO recollection of that at all :(

This is a really silly example but it happens ALL THE TIME. The events are just completely gone from my brain. Poof, nothing. This causes alot of fear for me and I’m worried I’m getting Alzheimer’s or something.. maybe I’m overreacting but something is wrong. I know myself well enough. My “memory loss” (if that’s what you wanna call it) has progressively gotten worse over the last year… my fiance and others get frustrated bc they think I’m just not listening but the truth is that I just don’t remember. I need help
