I struggle with feeling confident...

Hi, I’m not very confident in my skin. I feel unhealthy, because of my weight (160), but I eat nutritious foods. I have stretch marks from a few years ago when I wasn’t being very active and gained a few pounds.

I want to loose weight, loose my stretch marks and gain my confidence back. Is there any tips for weight loss (diet/exercise) and tricks to get rid of stretch marks? Thanks!
