I think a libre would help you as it has the alarm , it has really helped me. I am also very slim and find it hard to put on weight . I set my alarm at 4.3 so I have plenty of warning of hypos coming. Also try to eat little and often, I have a small appetite and eat a lot of cereal bars and small bananas which helps to keep my sugars more stable. I hope this helps as it’s horrible. I also used to get panic attacks after experiencing several horrible hypos whilst out shopping, now I have the lubrex2 with the alarm it has given me more confidence.
