Middle Age Group

I'm 61 yrs old. I hace been tryung to lose weight my ENTIRE LIFE!!! I'm making this choice now to live a healthy life and to live longer. My belated dad and grandmother suffered with obesity as well and both passed away before they were 64 years old. I have the same body frame and size just like them. My clock is ticking. I'm so sick and tired of living lije this. My legs and knees hurt all day long. I'm almost down about 80 pds. I have to reduce 120 more. My highest was 275. Currently i weigh 295. Would you please tell me how to join this group. I really need support. I'm very confident that i will finally get this weight off of me. Very sick and tired of living in pain.
