300+ Woman trying this all over again

Hello! I have struggled with my weight all my life. I was an average size toddler but quickly grew overweight as a child and then into a teenager. Topping at 315 I luckily was introduced to jazz exercise as a freshman in high school and fell in love with it. By middle of my sophomore year I was down to 210 lbs. It did not stop there though, I continued my journey and dropped down to 160 in my late teens early 20's. Unfortunately I did do it so healthy, I struggled with bulimia and over exercising the whole time. I would work out twice a day 7 days a week and run 3 miles 6 days of the week. When I burnt myself out I quickly began to gain it all back. Fast forward 10 years later and here I am again 320+ lbs and starting again from negative square 1. This time I am determined to do it right and using healthy methods. It has been 2 months and have dropped 15lbs and still trying to get right was it best for me. I have sought out some help with meals and work outs but would love the help and support from others. Last time I did it alone hiding my nasty habits and this time I am ready to be open with how I will accomplish my goal of 190lbs. If anyone can help a fat girl out? lol I will always be open to comments and suggestions. And most importantly if there is anyone struggling with anything I went through I may not be a professional but I am here if anyone needs to chat.
