Getting serious about losing weight at 308 (ugh)

My weight has been a long time struggle in my life. I topped out at 360 about 3 years ago. I haven't really focused on losing weight until now though. The other 52 was lost due just being active at work. But now it's time to buckle down. I'm 34, signing divorce papers in a month, single mom, student extrodianre. I have this new chance at life to be happy and have a real career instead of working food service. But most importantly I have this amazing kid who needs me to be around. It makes me feel so bad when I can't play with her outside for long periods of time without getting winded or needing to sit down. I don't want her seeing my unhealthy relationship with food and developing the same problems I have. So it's time to get serious and do the thing. I have been going at it since March 2nd (switched to vegetarian, counting calories and working out). Today I weighed in at 294. I'm under 300 lbs for the first time in 4 years. But even better, I got offered a cookie yesterday and my kid said "nah my mom is only eating healthy choices and so am I" and she turned down the cookie in favor of a pear. Little victories right.
