It's good that you're looking forward, because beating yourself up over the last few weeks won't change anything or help anything.

I'm having a similar time with not wanting to be around anything but grains but I'm doing my best to find alternatives. I'm not perfect and not aiming to be, but improved is worth it (eg. one or two lollies instead of a packet).

Baked beans in a can are helping fill that void, so are freshly cooked store-bought chicken wraps (my local takes the meat straight off the whole cooked chicken in front of us, so less chance of having 32 ingredients like Subway chicken has), and yeah fruit toast with butter has made its way in too.

I wouldn't be too hard on yourself for not being perfect, just aim for better. Then if you're ready, aim for better on top of that.
