I've lost weight from 60 kg to 56 kg. It doesn't seem like much, but it feels like a lot for my body. The puffiness in my face is gone, and my hip measurements went from 101 cm to 96 cm, and I'm 155 cm tall. My clothes, which I bought back in 2019, now fit perfectly and don't feel tight anywhere – I can wear them comfortably. I want to be happy, but I have this fear of being too thin, you know? Even though this is what I wanted. I didn't lose weight suddenly; it was gradual over the course of a year. My appetite is good, and I still eat sweets like before. I just started walking more, sleeping better, and my nose isn't stuffy anymore. It's upsetting that one side of my face has drooped while the other looks normal. I'm 37 years old now. If the situation with my face gets worse, I'm thinking of getting a facelift between 40 and 42. Most doctors won't do it before 40.
