sure.....but worried
In regards to your blood sugar, avoid the refined sugars (like sugar, white bread, cakes, etc) they give a quick but not sustaining sugar rush and increase insulin resistance and cause rebounding problems. The complex carbohydrates are better (multi grain breads for instance) for gradually raising BS (helps with the shakes) and sustaining it.
Do you have anyone you can talk with about your feelings about your marriage and friends? Therapist, counselor, friend, priest??? It is natural to sense some changes in your relationships, but it doesn't mean things are bad or were fake before or whatever. Just as your body has been changing, so does your mental makeup and that affects other people perceptions too. Seek professional help if this is a real issue or concern for you.
Good luck figuring things out!!!
