Hello,
It is good to know that you will be marrying a person you love. You have not stated anything about your past history or illness. It looks like in the past you have passed through neglect or abuse/ stressful event, a major illness, etc.
Since you are losing interest in daily activities you might be suffering from clinical
depression,
anhedonia or pedophobia.
There are many young women who are afraid to raise a child because it is a full-time job & requires sacrifice. Insecurity is another major factor that is making you restless.
If you are not mentally set for marriage then take your time. Don't force marriage on yourself rather help yourself prepare for it. Marriage is a big event you need to first get mentally & physically fit for it. Take your sweet time.
In my opinion, you should visit a counselor or a
psychiatrist & discuss openly how you feel. You may need some medication,
physiotherapy &
talk therapy. You may require to go through some blood tests & Imaging tests. Your treatment will depend upon the pathology detected.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
