How do I manage to lose weight?

Good evening friends,

I'm just going to write now and hope it reaches a few people so that maybe I and others can finally lose weight and get healthy!

I currently weigh 154 kg and am 188 cm tall. I'm still quite young, but I've always had a bit of weight on me, although back then I wasn't as overweight as I am now. I've been trying to lose weight for years, I know all the stuff… but I can never seem to stick with it. I think it might be because I associate food with comfort. Whenever I'm stressed or sad, I eat. No matter what, I just eat it. Afterwards I feel bad, of course, because I know it didn't have to be. But in that moment my head ignores everything else, all other "smart" things, and just tells me to eat, that it's not so "bad".

But honestly, I'm fed up with it. I don't have friends I go out with, simply because I think I'm not good enough. Which might sound like nonsense to some, but unfortunately, for me, it's a daily reality. I literally feel fat, and I am. I'm disgusted with myself, but I still can't manage to change anything?!
Since I'm a tall woman anyway, it's even more noticeable. The people around me are so beautifully slim, and every time I think about it, I wish I could be that slim too. I also wonder from time to time whether I should change anything at all—don't get me wrong! I want to lose weight to be healthy. I can feel how heavy I really am just by climbing stairs, or if I lie on the same side in bed for a short time, my legs start to hurt. The fact is, I'd have to lose 60-70 kg, and I wonder if it would even look nice and "healthy" afterward…

I look forward to any advice. ❤️
