is my friend a hater?

sorry this is long but i gotta vent. I’ve been friends with this girl since freshman year of high school, we are now 23 Basically i was a chubby girl pretty much all of our friendship, the ugly duckling of the friend group pretty much not saying i was ugly but i got the least attention from guys i guess. Long story short, i lost a bunch of weight and got braces in the last 2 1/2 years & i started looking and feeling the best i ever have in all my life. I grew into my body meaning i always had hips and a small waist s/o to my genetics lol so i started getting a lot of attention from ppl in general. While i was growing and glowing my friend was gaining weight. she was a slim girl all her life so she was struggling with her new body. I have always thought she was beautiful so she didn’t look different or bad to me. Anyways i started noticing that when i ask her to take pics of me her whole vibe changes and she takes the worst pics while I’m taking really good pics of her ik they’re good bc she tells me that i take the best pics! so i started thinking negatively of myself bc all my pics would be so ugly. so Basically i started having my 12 year old little sister to start taking my pics and when i tell you she makes me feel and look like a model & i realized how different the vibes are so i then noticed that my friend low key puts me down with backhanded compliments and the way she tells me i still look like how i did when we met ALL the time. Even my baby sis was like she thinks the pics look like my friend deliberately is getting the worst angles or makes them blurry or angles it weird. idk maybe I’m over thinking it 😩
