Feeling dizzy

[Newyearsameoldme2020]

I've been feeling dizzy all night, as if I'm going to faint. Is there anything i can do to help?
Only posting here as I'm home alone with 2 young kids and no one to advise me. We don't have 111 in this country.

When did you last eat ?

This is what the uk health service advise

Things you can do to prevent fainting
If you feel like you are about to faint, try to:
• lie down with your legs raised – if you cannot do this then sit with your head lowered between your knees
• drink some water
• eat something
• take some deep breaths
