@25yearsnhsworker - Hello and welcome to my thread! 
I know how you feel about hitting rock bottom, I was like that in May this year, hence I decided to do something about it. I guess for me, I just bit the bullet and started the very next day, and to be honest, I've not really looked back since. My biggest problem with losing weight is discipline. I am addicted to junk food, and need to rely on party food as a means to get through each day, it was my best friend and formed a big part of my daily routine. I always had a big bag of salted peanuts opened and sat on the worksurface in the kitchen ready for me to dip my hand into and grab a load of nuts, or a big multi pack bag of crisps next to the fridge to tuck into every time I walked past.
Now, I don't allow any bad foods in the house, and so there are no temptations, no treats, nothing. When we go shopping, we don't go near the cakes, crisps, biscuits, chocolate etc, and I don't miss it one bit. The kick I used to get out of eating a bag of crisps lasted maybe 10mins, but the kick I get out of losing just 1lbs lasts for days, as does the enjoyment of being able to wear literally anything I want.
I also very much enjoy fitting in car seats, plane seats, not having painful knees whenever I climb the stairs or a ladder. I like sleeping properly too.
I also really like it when I meet people I haven't seen for say 6 months...and they genuinely don't recognise me, to begin with. That's very rewarding indeed.
Above all, my mental health is so much better. For the past 3 years I have suffered intermittent stomach pains, indigestion and acid reflux. For years, I was constantly worried that there was something very seriously wrong with me, primarily bowl or stomach cancer. I was prescribed Omeprazole but that didn't do any good at all and the worries just occupied my thoughts day and night. 
Since losing 54lbs, and am pleased to say ALL my ailments have disappeared and I am very confident that I am not terminally ill. If only I had of known these past few years that all I had to do was lose weight and get healthy, I wouldn't have gone through so much hell.
I stopped going to Slimming World when my 12 weeks paid sessions were up and decided not to continue. There was absolutely nothing wrong with Slimming World, in fact I can only sing their praises and thank them for showing me a new way to manage my eating habits. However, I choose to leave because I wasn't following their recipes yet I was still losing weight.
As regards my typical day of food, well, it's not good at all, but it works for me and here it is:
Breakfast - 150g of Skye fat free yoghurt with 30g of granola. = 180kcal
Midmorning snack - 1 boiled egg = 70kcal
Lunch - 1 cuppa soup and an apple = 190kcal
Evening meal - Ham & Chicken Salad with lettuce, pickled onions & Cucumber on a small plate, plus a sugar free diet jelly for afters = 150kcal
I also drink a few cups of coffee with sweeteners and skimmed milk, and a few glasses of water throughout the day. = 50kcal
Total = 640kcal
Quite a strict diet, but then since losing weight I no longer have the big appetite I used to have and as I am keeping active all day, I am possibly burning 1,800-2,500kcals a day.
I have no idea where all this is going to end, I estimate I still have 2-3 stone left to lose, maybe more. I take each day as it comes, but overall I know I can never go back to eating the way I used to, or else these past 4-5 months would have been a complete waste of time.
