Big Goals-Need Help

Hey all- I'm new to this. My weight has been up and down all my life but I am now the biggest I have ever been. I think it's starting to affect my energy, mood, and overall happiness. I want to try to lose 85 pounds and I know it's going to be extremely hard for me. I never eat because I'm hungry. I eat because I'm bored and I know I need to get up and do things. I am going to need a lot of support and motivation from others- I know this about myself. Any tips would be appreciated too.
