Hello there,
Not being able to sleep can have a lot of reasons, one of which might be preoccupation with thoughts regarding what might not be working for us in our lives right now. Accompanying stomach ache and headaches might be indicative of increased stress levels, conveyed by the body. I would suggest that you try and maintain sleep hygeine, like keeping a fixed sleeping schedule, reducing screentime, caffeine, and heavy meals. You could try calming exercises like deep breathing, stretching your muscles, listening to calming music just before you sleep to help you with falling asleep.
You could start journaling or talk to someone close, about your feelings and concerns regarding your career.
Next Steps
You could reach out to a therapist for further understanding the situation and guiding you through it with support.
