I wanna lose weight

Daisy
I've been wanting to lose weight for a while now, I was skinny a while back, I realized I was getting fat from my stomach, my waist was getting wider too, and my funny is more chubbier, and this was like around December of last year, and since then I've wanted to lose weight, I used to weigh 115-120, I went to my physical last month, now I weigh 136 pounds, I was a size 2 and now a size 4 or 6, I wanna go back to my size 2, can someone give some advice on how to lose weight and doing all that at home please 😭😭
