Thyroid :: Extreme Weight Gain With Hashimoto

I don't really know how to begin this message, I'm so exhausted and mad against that weight gain and stuff.

I am 20 years old and was diagnosed with Hashimoto one year ago. Since then, I put up 20 kilos ( most of them in 6 months ). My t4f and t3f are okay, and THIS is at 0.40, which is the minimum.

There are two years and a half ago, I was 110 kilos. I decided to lose weight and did 2 to 3 hours of sport per day + a diet. I lost 54 kilos and reached 56 kilos for 180. I felt soo good and happy for the first time of my life, no kidding.

And then, I haven't even had the time to have fun with my new body, that I began putting up weight.

I do 10 to 14 hours of sport per week ( I run a lot, quick walks in the mountain and so on ) and still follow my diet ( 1200-1300 cal )
I'm sick, I'm trying not to be too depressed, but it's hard. I'm so tired, my muscles don't want to keep on, and neither want I. Thinking that I've lost one year of my life trying to lose weight for nothing makes me mad.

I'm followed by a diet doctor, who can't even find why I keep on putting weight,m but tries to change some of the aspects of what I eat. I also see a psy, he can't really help me, as my problem is real, and not just in my head.
