Morning I am confusing myself by posting on other threads as well ,morning average etc, but I am easily confused

I will just repeat myself, here goes
Last night 8.30, bs 10 had a small bowl of fruit
bed bs 6.1 (hoped fruit had stopped working, was I wrong ?)
9am 12.1 woke up at 5am and couldnt sleep, now realise bs too high.
I am not doing too well at this and feel pretty bad now from high bs and lack of sleep. Do you think it was the fruit ? I should have injected with it, didnt because I was nervous from night before and when bs was 6 at bed assumed everything would be either ok or I would go hypo again, help please TinTin
