Hi Nayxcore,
Yes you can recover, it will be a long journey.
I'm struggling with mine at the moment, I've beaten it before but, struggle to maintain it.
I feel guilty when I gain and I feel guilty when I lose. Before when I lost weight, I would feel happy but, it doesn't last long.
Try eating small amounts at first and then increase it. Don't do what I use to do - I would eat large portions and the guilt would set in and I would go back to my old ways.
Set yourself small targets.
