I’m somehow shrinking

[Lowtiergod✌🏽]

I’m currently 15 and was measured at 6,1 with no shoes and throughout 2 months I feel shorter and messered myself now at 6ft. I feel like I’m going crazy, is there any reasons why I’m feeling like this?

Either:
1. Mismeasured
2. Spinal compression from poor sleep and/or dehydration
3.Posture
True shrinking starts at 40-50, are you 40-50?

I’m mostly positive I’m not mismeasured, the only thing I can think of spinal compression is that I do heavy squats. But I have good form and posture and track my diet so I don’t really know.
