Iso t1D female friends who want to only lose 15lbs.

Iso t1D female friends who want to only lose 15lbs. - the 15lbs that will bring you to your happy weight place, like your weight in grade 12 when you were 17.....
I've had 1 baby at age 30 and I'm 37 years old now. My only excuse to gaining weight is poor attitude about losing and no counting calories for about a year now. I have t1d for 27 years. I take humalog and tresiba. Also metformin to reduce my insulin because endo said less insulin helps with weight loss.
If you have same goal, please add me and we can support each other. I have no support at home. My husband is overweight, smokes and doesn't care about health.
