Welcome back sweetie!
What a hard time you had. My DD has a similar background. I wish she would try a LC lifestyle to help with bipolar disease. Many of her medications make her hungry and make her gain weight. When she is manic, the weight drops dramatically. She started out at 98 lbs and now is 256 lbs. We know that the medications she takes are critical to her mental health, but they will make her gain weight. It does not help that she eats poorly. Fast food junk, pop, sugar, candy, cookies, etc.

Looks like you are doing the right thing by taking control of your health by using a LCHF/keto lifestyle. Keep up the good work!
