Feeling Really Insecure.

You ladies have any tips to “glow up?” I struggle with my skin, blackheads and body acne specifically. My pores on my arms/shoulders/neck/back/boobs are very apparent and clogged looking. I struggle with blackheads all over my body and i need help!! I’m also just looking for tips for losing weight and overall confidence. PLEASE help, my mom and sister never taught me how to do anything i had to learn it all myself and i feel so lost! I’ve included pictures of myself and am looking for advice on how i can overall better myself :)
