hey there allie!
try not to let the scales rule you. a great option is to take your measurements & write them down, with your weight and today's date. pop it in an envelope, seal it & stick it to your fridge, and write down a date for in say 3 months time. between now and then, let your trainer take your details but don't you look at them or anything - wait until the big date....
you'll see a more consistent pattern of loss when doing all the right things, and not obsessing each day or week about the numbers. that kind of constant checking, feeling bad and possibly having a blowout in response does nothing for your focus, motivation or state of mind (trust me i've been there - been a serial weigher!!)
i've been training for over 9 years now, and to this day have not been overly pleased with results, and have myself gone down those paths & cycles of self hate, defeatism and sabotage, feeling like a failure or that it's not working... so this past year i've been doing a lot more work on the progressive & psychological side of things in order to achieve more balance, happiness and a sense of success.
by taking a few different strategies on board like the envelope one above, you will save yourself a lot of stress and disappointment. rather than waste energy on those empty feelings, use the space to continue working on your good eating and exercising. shifting focus just slightly can be a long term saviour in that respect.
