Anyone else struggle with feeling increasingly unsexy?

Hello! I’m 37/f and I always had body image issues but recent weight gain and just aging in general has me feeling awful about my appearance and not even remotely sexy anymore. It’s tanked my libido and it’s making me depressed.

Im unmarried, don’t have children, and workout every day (cardio, barre, and strength training/weight lifting). I could be better about food and alcohol. I’m trying to get better sleep habits, drink more water, and drink less booze. I think a lot of my worth is tied to my sexual attractiveness. Every day I look in the mirror it gets worse and worse and I’m often so depressed about it that I start crying. If someone takes a photo of me it sends me into a spiral so bad that it takes hours to recover.

Has anyone gone through this? It only started happening after 35 or so. I don’t know if I’m looking for advice or camaraderie but either is appreciated.
