I'm at my heaviest

Hi everyone my name is Lutèce and I'm 25 years old. I'm 57.3 kg and 5'1.5". I used to be really into my fitness but in recent years my lifestyle has had to change and I've found it difficult to keep up with the training and diet. I want to get back to being 51kg and strong like before. I'd be really appreciative if you guys could help support/motivate me and get me to my goal. I'll support you all back ☺️
