Feeling discouraged

Options
This coming Saturday will mark 3 weeks on MFP. Maybe it's totally unrealistic to see weightloss in this time frame or maybe my calories are off but I'm just not losing. :frown: I'm in college and a lot of nutritional information is not available in the dining hall so I have to guesstimate a lot so maybe that's it?

My diary is open and I would be grateful for any encouragement or advice.!
