Weight problems

I feel like crying, over the past 2 years after high school i've put on like 50 pounds, I struggled with weight my whole life and so when I was younger I used to starve myself to keep it at bay, instead of losing it would keep it at a stand still which scares me because i wouldnt eat for weeks at a time and wouldnt lose any weight at all. Now that i've put on weight like crazy even though I eat only veggies and lean meat, and no junk, maybe 2 cups of food each day, and play sports and go the gym for hours everyday. I feel like I have a problem and i dont have the money yet to go to the doctor. Ive gained 10 pounds in a single month and it just keeps climbing, i stopped eating 3 weeks ago, i dont know what else to do, i used to be a healthy weight and now im obese, and i dont even know why 😪😪 5'2 and 200 pounds now
