Dear Ma'am,
It may definitely be tough to go through these concerns. Sleep difficulties, tightness in chest, headaches and gastrointestinal problems may both be a sign of a physical or psychological difficulty, or both.
It is important for you to seek medical as well as psychological help to evaluate what may be causing these health disturbances.
Next Steps
Seek help from a family physician to rule out physical problems. And, also consult a psychologist thereafter.
Health Tips
Remember our mind and body are connected. Physical health may impact mental health and definitely vice-versa
