I was in a very similar situation at the start of the year. I had a terrible diet, no energy, felt shit about myself and was also in the obese category.
12 weeks later, I’m a different person. I’ve lost just under one and a half stone and 4 inches off my waist. So it’s possible to change and see results pretty fast!
I’ve been following the NHS 12 week weight loss plan, which is a pretty sensible plan that teaches you about healthy eating at the same time. You can find it here:

The most surprising thing for me was that after the first 10 days, it became a very easy diet to follow. Which is just as well, as I’ll need to be on it a bit longer before I am a healthy weight.
I recommend that, with whatever diet you choose, you find things to keep you distracted over those first few weeks and especially around times when you normally snack.
Also plan little (non food!) rewards to get you through those first few weeks.
Finally, try not to focus too much on where you want to be. Losing two stone can feel like an impossible task, but losing 1 or 2 lbs a week sounds totally doable. Both will get you to exactly the same end point eventually.
Oh, and the exercise bit is kind of optional. It’s unlikely to contribute loads to your weight loss, but could help to make you feel a lot better very quickly. It doesn’t have to be strenuous. I aim for about a half an hour walk each day.
Phew, that turned into a pretty long post. But in summary, you can totally do this, if you want to!
