Redeem yourself? You make it sound so bad. Don't worry, you'll be fine.
You admit that your diet "never ever changes." That's entirely under your control, and it's the most important factor for losing weight or fat. It's quite realistic to lose 8lb in 8-12 weeks, if you get on a balanced diet and then get into a calorie deficit of 500kcal/day (so, if you use up 2,000kcal/day (which is fairly average), you'd be consuming 500kcal less than that, ie 1,500kcal/day). Your return to exercise will probably increase energy expenditure by about 300kcal/day, so you'd only be looking at about a 10% reduction in calorie intake (achieved fairly easily by reducing portion sizes by 10% or by omitting 1 snack) to get to about the right level and lose ~1lb/wk.
What sort of exercise are you doing? When it comes to changing body composition, people tend to get their exercise priorities the wrong way around, focusing mostly on low intensity cardio and minimally on heavy lifting (heavy being relative to your ability to perform the exercise with good technique), whereas heavy lifting will have the most impact on body composition and low intensity cardio is realistically not very important for the goal. While strength training builds muscle when in a calorie surplus (consuming more energy than you expend each day; the opposite of the deficit that you're after), it maintains/preserved muscle while in a calorie deficit, optimising the amount of fat lost amongst weight loss. That is to say that if you lose 8lb while doing heavy strength training, you will lose a better 8lb than if lose the same weight without heavy strength training. As you're more concerned with inches than the number on the scale, this should be a particular highlight to you.
