I'm also wondering why they gave you such a small amount and I think they may be worried about you misusing it, for whatever reason. I have diazepam, not for anxiety (although I have that too, I take propranolol for it) but for when things in life become extremely stressful and I need to zone out for a while. I don't have a regular prescription for it, but the doc seems happy enough to prescribe it when I ask, once he's checked that from my records that I'm not taking it regularly. I usually get about thirty 10mg tablets at a time!
Your GP is verging on being negligent prescribing you that many 10mg tablets all at once.
