Feel like an absolute idiot for letting myself gain my weight back

Idk who reported my previous post and for what but one year ago I was at my GW (I was around 19 then), I was eating healthy, working out and super disciplined. And then I moved away for college and my sole nutrition source became ramen and pasta. I began eating chips and sugar and chocolate again and I basically stopped working out cause my asthma got worse and I put all the weight back on and I feel like an f-ing idiot. I'm trying to get back on track but the weight gain's demotivated me and made me feel like there's no point. I need help getting back on track because every attempt so far has resulted in absolute failure and bingeing
