Try relying on your doctor if the family members are not understanding enough. Feel free to ask any questions you may have, as they will not be judging.
When I first got diagnosed I used to have over 10 alarms set on my phone to remind me to eat, snack, take my long-acting insulin, even for a light exercise before bed. At first they were really annoying but then I realized how much they helped me cope with everything. When I started getting used to the routine I didn't use the alarms anymore.
