Hi... Being an introvert is a personality trait and a preference, not a disqualification. What you are facing here is an adjustment issue.
It becomes even more relevant when it is marital setup where one is expected to change and adapt to newer ways of doing things.
You can develop your social skills to deal with this newer environment and adjust to it in a better way without changing your core personality trait, i.e., Introversion.
You have mentioned your diagnosed condition as Epilepsy and the medication you are taking. This condition requires both medication and therapy/counselling along with neurological intervention.
Next Steps
Please consult a Neurologist first and then a Psychologist for Counselling.
