Pain in the lower abdomen

I'm 168 cm tall, weigh 52 kg, but my double chin still hasn't gone away. Everyone recommends getting my double chin done, so I'm thinking about getting it done only. For those who have had it done, how's the recovery period?? I'm curious about how long the bruising and swelling last. And the pain from the surgery varies so much from person to person.. I'm scared ㅠㅠ I remember not being able to sleep well after getting my nose done again a while ago, so I'm freaking out.. Do many people get my double chin done?? If you're only going to get my double chin done, won't the swelling go down a lot??? Below is a picture of my double chin, lol. I really don't have a chin. It's even red because I had Inmode that day. Jiheop. Should I get it done even though it's scary? ㅠㅠㅠ
