I need help with weight loss please!

I hate myself. I hate my body. This isn’t a body I can grow to love. This isn’t a body I can learn to love. The only way I can love myself is to change myself. I want to lose weight so bad. I have tried countless times and each time I never last.

It’s so pathetic.

Each time I tell myself “This will be the one“. It never is though and I am beginning to give up and except that I’ll never be happy with who I am. I need to do this. I need to lose weight. My senior pictures are coming up in two months and I want to lose some before then. I don’t know how much would be healthy for a two month. But I’m thinking 15 pounds? Or more. Please help. Please. I need advice, I need support, I need motivation. I’m 192 pounds and I’d like to get down to 165. How long will that take? What do I need to do? I’m 5

foot two and 17 years old. Most of my weight is in my stomach and my thighs. Please give me any advice you can.
