It is extreme. However it only becomes an ‘issue’ when it happens frequently. It’s honestly horrible so I’m hoping it doesn’t happen her very often. I find it happens to me when I’ve been working all day and haven’t gone outside. I think she needs to go for a big long hour or hour and a half walk! Fresh air into her lungs; it’ll tire her out and help her sleep at night.She mentions went to bed at 21:30 but couldn't sleep until 5? I have trouble falling asleep too but that is very extreme....
She’s probably mentally tired from studying but not physically tired enough to sleep. Self care is so important.
