OP it’s ok, don’t feel embarrassed or ashamed, we live with ready access to hyperpatable foods and add in stress, modern life and mental health it’s very easy to get out of control.
can you go to the gp and get them to check you over? Blood pressure, liver function, cholesterol, blood sugar etc? Give yourself a baseline and to know if there is anything that needs medical attention.
the nhs does have weight management, it might be worth asking about it and seeing what you are eligible for. I had some tier two support but it was a bit crappy.
WLI do work, but they have become more expensive and come with side effects and the knowledge that you will have to come off at some point. I’ve lost 5.5st and now feel a bit trapped by them until I sort my head and diet out so I can maintain afterwards.
Id recommend weighing yourself, taking some measurements and taking some photos you never have to look at.
Start small, tiny even. Decide on some non-negotiables, that might be 1.5 litres of water, 3000 steps and one fruit and vegetable a day or something. And just get used to that. I’d also find a tracking app and track everything you eat, weigh it, measure it and be honest. Don’t try and diet, just look at current consumption for a week or two. Then spend some time looking at quick fixes, decrease 100 calories, add in 5 minutes of exercise. See what that does. And keep going.
whatever you are doing you need to do forever, lose the weight in the slowest most sustainable way possible. Know your bmr and decide on a small deficit, one that feels manageable.
You will have bad days, moments, meals, draw a line and carry on to the next moment, meal, day. The thing that works is showing up every day and trying.
If you don’t want to go tk the gym, don’t. Weight loss is about diet, you’ll want to do some exercise but walking, using resistance bands and following low impact Pilates videos on YouTube will do that for you until you want to go to the gym.
if you can afford it book to see a PT that works with nutrition and understands obesity, having a cheerleader can be really helpful.
good luck, your value is not defined by your size and you deserve to be happy and feel beautiful.
