No one here can give you any trite simple answers - those wouldn’t work anyway.
Diabetes is awful. Annoying. Debilitating. Relentless. Depressing. Limiting.
But
It is also manageable. Doable. Squashable. Limitable. And if not completely ‘beatable’, then certainly something that can (one small step at a time) be kept in its place and made to fit into your life, rather than the other way around.
Of course some times it will feel overwhelming, and the end of everything. But there are chinks of light and occasional diabetes victories that can help you realise you are winning, and not beaten.
Keep going.
