100 pound weight loss goal

Hey guys my name is Jesse. I have struggled with weight since I was 11 and tore my acl. From not being able to do much physical activity without knee pain to knee surgery at 18 and spending time in a wheel chair or on crutches for 6 months after. I got to the weight of 275 my highest ever and I realized I needed to make a change. I am 12 lbs down and hoping to keep at it. Any friends who are in the same position would be appreciated .
