I just don't know what to do...help!

I just dont know what to do! Yesterday I was feeling like total crap mentally (day 11). I could keep going on, but I just dont really want to. My head is not into it. I actually ate a small salad last night. Got up this morning feeling like "What did I just do", I can't stop. When I put on a shirt this morning that I hadn't worn for a couple years (too small) and it fit, it gave me some new incentive! But today at the end of the day, I feel like "i don't really want to do this anymore". :(

Do I force myself to try and keep going, or should I stop and do it another time when my mental motivation is more there.

Btw....my tongue is suddently pink again. Is this cuz I ate the salad and my body stopped detoxifying?
