Don't give up, just take each week by week, try not to look to far ahead and focus on now, I'm losing weight at the moment also, and before I always looked too far ahead wishful thinking how good it will be when I lost all the weight, but then I would have a bad week and not lose anything or maybe only half a pound and it was so hard to take, it really demoralises you, so I'v learned to work for that week and make the next weigh in day the challenge , to beat the week before, and not focus on what's to come in the many months ahead,
This has helped me as the week goes fast, and week by week the weight will come off and you will see results and be happy
( tho mine is on a standstill at the moment, but hopefully found the problem
good luck on your journey
