I can’t recognize myself In the mirror

What can we consider normal? Is staring at your own reflection and not seeing yourself normal? Because it’s becoming normal to me now. It’s been going on for a while now, every morning I look at myself in the mirror for 5-10 minutes and try to recognize the person in the mirror but with no luck, I put on my makeup do it again but i still can’t recognize myself, go to school come back look in the mirror once more, same thing, take a shower before bed look in the mirror one last time and again no one. I can’t explain what I look like, or who is looking back at me, when I look it feels like it’s the reflection of someone that looks like me but doesn’t, when I try to look harder I feel even more disconnected to the person in front of me, every time I try to smile, frown, look angry, perplexed, sad, ect it feels like someone’s looking back at me but it’s not myself. What I do know is that when I look at myself in the mirror an overwhelming anxiousness comes over me, I feel my chest sort of tighten and my breathing get shaky, I sometimes even start to tear up. I’ve been feeling really dull lately, and pretty sad, anxious and depressed so maybe that plays a role in it? I’m so confused, the person in the mirror is me but not really me? It’s someone that’s there looking at me but not being me, I need help, please.
