Momentary dip in confidence

This is just me sharing my momentary blip in confidence, and feeling of fear in not achieving any significant weight-loss. I know this is just a blip and probably due to a crappy cold coming kn but, I'm so scared I won't finally break the 200lbs. I have been bouncing between 245lbs and 259lbs for YEARS and I am desperate to even see 230s and break that imaginary line.

I am starting week 11 (third shot of 1mg yesterday) and I am down from 258lbs to 242lbs but I've been at 242 for two weeks. I'm eating between 1200 and 1400 calories, tracking everything I eat, getting in protein and water, hitting 7K to 10K of steps a day. I know I am doing it right, and am seeing a some loss so why am I feeling nervous that im not going to break that 240lbs number?!?!

Does anyone ever feel scared it's not going to 'work' out of the blue? I am a positive gal usually but this came out of the blue.
