I’ve had a difficult few weeks, mainly due to confusion regarding my ex partner and stomach issues.

This has led to some insomnia which I now can’t stop worrying about. For the past week or so I’ve been waking up multiple times during the night struggling to fall back asleep.
As a result, I’ve been only getting around 4-5 hours sleep per night in total.

Cue the panic, been thinking how this isn’t going to get better, that I’m going to lose my hair, become ill etc etc

I would really appreciate some advice and tips on how to get over this. Thank you as always to everyone on here.
