I've lost an inch. I was 5' 5.5".
However, I've always thought of myself as being tall. I had 2 women friends - one was 6' tall, the other 6'1". I'd say something about "tall people like us", perfectly seriously. And that was when each of them (in different decades in my life) hauled me to a full-length mirror to prove to me that I was significantly shorter than them.
I always thought of my husband and I as being close to the same height; he was 6'2".
One time I planted some flowers in a tiny flower bed. I measured it and was 6' long. Yup, 6' is not long at all.
Aside from being delusional about my height, I do wonder how that could happen. As in, what is wrong with my perception? I still feel tall, I just don't talk about it. One time at work, a woman was complaining about how she hated being short. I asked her how tall she was and we were the same height. I was flabbergasted that she would think that was short! I told her that was complete BS since we are the same height and I am TALL!
