I need advice

I’ve wanted to lose weight so bad for years now. I am 4’11 and started from 120 to 190. I gained this in 5 years. For some reason I just can’t get myself to care. I’m lazy, I tell myself “okay ima eat better and start doing better” and then boom I forget I even told myself I was going to do it all. My doctors have told me I have pre diabetes, you would think I would change. I feel so addicted to food. I’m at a lost. Just want to cry, but I just have no care to try. Idk how to change. Because I hate looking so fat & feeling gross. But I don’t wanna put the efforts.
