Good day Friend, I can understand your concern.
Be aware that our body and mind are closely interconnected. Means any emotional disturbances to your mind can easily affect the physical functions of body by causing sleeplessness, headache, lack of appreciate, Menstural issues, PCOD, weight gain or loss, body heat and many more.
If you try to understand the root cause behind all these problems, it's your overthinking or overwhelming negative thoughts!!
So instead of addressing symptoms it important to address the root Cause.
Be positive. It's an addressable issue if are willing to make few changes in your mind set and lifestyle.
Feel free to reach me online for further assistance. Be positive. You will be alright soon.
Health Tips
Be aware that there is no one fit for all solution especially when dealing with emotions and thoughts. General advice and google doctors will not help here. You would need a counselling help first to ventilate your feelings, emotions and concern. Then suitable solutions can be worked out.
