My question, has yours been a life worth living. If you had a choice before you were born would you still have chosen life for yourself. A life with diabetes is a struggle but it is still a life worth living. Its a life I would not reject even if I had a choice.
Life is precious no matter the struggle, You gave your daughter life, you gave her the best you had to offer, you gave her a part of you. Diabetes is only a minute part of that.
Please do not feel guilty, you did your wonderful best. Rejoice in the miracle that you helped create.
