weight loss help

this is really stupid and somewhat probably going to be hard for anyone to help but I need help and motivation to lose weight . I have a hard time saying no to any kinds of food , I can barley drink water and I'm to insecure to go to the gym to even try . I have a really really big problem with what people think about me and my appearance and with that being said it tears me down and makes me not want to try . I weigh about 260 pounds but I don't look like I would . I just need help with certain things and I don't have anyone that is willing to push me !! I NEED HELP lol
