Need motivation buddies.

I wasn't always heavy. I started gaining weight when college hit. I was still active but I put on 10 but i still had a lean body from sports and being very active. said okay no issue. 8 years pass and I went from 167lbs to 242 lbs. At about 230 I took a closer look at myself. Found I can't deny it anymore. I gained a lot of weight. 4 years of it on an athletes diet. Being able to intake 3000 calories was no problem. I don't get too much positive reinforcement from those I know and love with this. If they try it is usually lack luster and too varied for me to feel like I can keep going or they don't understand and tell me to suck it up and go it alone as best I can. Part of the reason It stalls over and over is because part of me believes I can't do it. I can't shake it. I was always a confident kid with talent so I have never moved that mountain any of you have before. I have never had to start at 0 and I really need that yoda to teach me how lol. Please help me with this journey as best you guys can. Thank you.
