Lose 25 pounds in a month..advice

Ana

I’m 27 and Im want to lose weight because I’m tired of being fat and tired all the time. My daughter is also ashamed by me and I say this because she said I look like the fat people on that show (my 600 pound life) I’m currently at 260 and I want to lose 25 pounds by next month. Is it possible? What are some things I can do to lose weight? I try fasting or eating less but it seems like I’m constantly getting headaches and even when I eat I feel like I still want more 😢 idk. Can I get some advice please?
