Struggling with Insecurity on Social Media

I am seriously being affected way too much by social media. Like I overthink the photos I have on my social media and I’m becoming way too critical and insecure over my pictures. I’m overthinking everything like what people see my photos, what they think, how many followers I have, if my selfies are too ugly, like it’s bad. I just posted a photo that I loved and lost so many followers and got such little likes and now I feel so insecure about myself. This is so unhealthy but I’m afraid to delete my account because I have a lot of old pictures saved on there that I want but if I just delete the app I always download it again and the vicious cycle starts up again. Idk why I feel this way, I never have before. I used to be secure with myself but now I’m so insecure with how I look and how I am I don’t want to feel this way.
