Being at admitted because of my levels

I'm being admitted to the hospital because of my blood sugar levels. (Im not on any medication)The highest ive had over the last week have been 280 and the lowest was 121. So im being admitted until they can bring it down to 90s...im so upset right now...hospitals frighten me and i feel alone and unprepared because i came with just my meds and notepad,thinking i was coming for a regular check up to start my insulin
