Hi Marylyn - Big Welcome to Pet Talk - sorry to hear you're having trouble getting a decent night's sleep. Things that I have tried over the years - and that appear to work are:-

Having a big mug of hot chocolate!
Eating lettuce - don't laugh - this really does work!!
A nice warm bath with lavendar oil - light candles if possible and turn out the main light - sooooo relaxing.
Sprinkling lavendar oil on your pillow.
Don't lie there worrying - get up and do something - I normally go downstairs and talk to the cats while brewing a cup of tea - sometimes I think it's just looking at sleeping cats that works!!!
Read a really boring book!

Hope one of these might help - but remember if your upset and worrying I doubt you'll manage to sleep - try a bit of relaxation.
Good Luck hope something works.

Lynne
