Ya girl got played dirty, help👇🏻

So my boyfriend of a yr broke up with me over my weight and other things and it really hurt and it's something I've always wanted to get rid of but I just don't know where to start, I've never really exercised so I need some routines and meal guides or what I should eat and what not to eat but mainly exercises I can do at home for beginners to lose weight every where and tone up and look hella fine af so he knows what he gave up and when he comes crawling back I can be all sexy and skinny and be like boy bye.
