Upcoming Weight-Loss Journey

Nya
I'm 19 years old ( just turned it in November ) and I'm not happy with my weight. Haven't been for a while but I have reached my breaking point today. As I was showering I felt rolls coming in not literally coming in but I felt them, ( yes at 19, PLEASE do NOT judge me ) just hear for some positive words, advice and positive stories. Decided that I will be going to the gym at least 3 times a week and work my way up for my timing at the gym. I wanna start off little by little. So right now my goal is just to eat primarily salads, drink plentyyyy of water, eliminate soda (barely drink soda unless it's seltzer or ginger ale for when I'm on period) etc. Please give me words of encouragement as I start this journey. I'm also super excited to start this journey! I'll keep you guys updated and in my update I'll have before and after pictures.
