Insomnia is driving me crazy

[TC Devon]

Hello
I’m having random bouts of insomnia. Last night I could not get to sleep. Even resorted to my daughters melatonin. I ended up with one hours sleep that included my 8 yo waking me for a hug!
Exhaustion got so bad I had quite bad chest pains.

Today I had to teach all day. It was not fun. I was nt on the ball. I made stupid mistakes in my teaching.

Does anyone else suffer, what do you take/do? I think it’s worse when I have my period. I do get quite low moods at these periods. It’s also worse when my husband is on nights. I’m on steroid tablets again (covid has destroyed my lungs) but I take them so early in the morning they should not be keeping me awake all night.

Frantically trying to work out the trigger.
