Trouble controlling appetite/weight and sudden rapid hair loss.

Hi. I'm a 22 year old overweight female.

I have been overweight my entire life. I was born weighing 9 lbs and began gaining a lot of weight at around 4 or 5 years old. I have never been at an average/normal weight for someone of my age and stature. My weight continues to go up, and whenever I get on diets I gain everything back. I can quickly lose 30 lbs but then gain 40 lbs just as fast. At my heaviest I weighed 287 lbs but currently I weigh 251 lbs.

I'm very lazy and don't have the motivation to exercise and I'm plagued by pain throughout my entire body, especially in my lower back. I was also diagnosed with Type 2 Diabetes around 6 months ago but for now my blood sugar is in a decent state.

I crave anything that is sweet (fruit, pastries, juice, etc.) and then immediately after will begin to crave salty food (cheese, chips, pretzels, etc). It creates a pattern. After my diabetes diagnosis I've tried replacing the sweets with sugar-free options, but I frequently find myself eating sweets even though I'm aware of my condition. I also do crash diets in which I refuse to eat anything for most of the day and will have 1 small meal at night.

I also eat even if I'm not hungry at all, and typically this consists of junk food (bread, chips, beef jerky, etc).

There is a new condition that I recently discovered. In the beginning of November I noticed that the part in my hair has become wider and I can see my scalp underneath my hair. My hair has begun falling out rapidly. It has become thin and I can feel the hair pop out when I brush it. I have chronic white dandruff and my hair becomes oily the day after washing, but all of the medical articles I have read say that dandruff does not cause hair loss.

I would appreciate it if someone could recommend some remedies for me. Thank you. :)
