On the shot

I forced myself to skip my Tirzepatide shot this week and I’m still struggling everyday to eat. All I had yesterday was half a 160 cal protein shake. So 80 calories the whole day and this keeps happening everyday. I can’t get any food down. I just want to be able to eat so I don’t faint again… I am in the normal bmi range so I’m not fat at all, just wanted to lose a bit more weight
