Some simple things to try might be lavender oil on your pillow, and try not to use electronic devices for an hour or so before bedtime.
I struggle with sleep and have done for many years but it has become much more pronounced over the last year or so. I sometimes head into the spare room as we have blackout blinds and curtains in there and the darkness really does help.
The most difficult thing when you lay down to sleep is that is the point where your thoughts and feelings come to the fore. Very difficult to manage but definitely seek help whether that’s help with counsellors, friends or even just allowing the members of the board to vent with and let off steam.
For all the different viewpoints and disagreements on here, the magic of this board is that when needed every person will be there to help another.
