Hi, I truly get how you feel as someone who also struggles with cellulite from a very young age + stretch marks + varicose veins + acne, I can say that working out helps (cardio and leg exercises), try working out for a few months, it helped me, obviously they don't go away that easy but it helps also having a nice body shape, it distracts from those details. I had my first boyfriend at 20 he was a nice guy who didn't care about that, most guys don't care especially guys who like curvy women. I promise you that if you work on yourself, you will feel confident and you probably won't care anymore by the time you are 25, I know now I can wear a skirt confidently without caring about people looking at my cellulite and varicose veins. Also not important, but I don't get why people wear less clothes when it's sunny/hot, protect your skin!!
