Hello,
welcome to Healthcare Magic.
Your above mentioned symptoms indicate presence of
depression in your case. Having smell of rotten eggs may be due to
olfactory hallucination. In presence of olfactory hallucination, it is better to rule out pathology in brain by MRI, which is already planned in your case.
Depression can cause somatic symptoms like headache and
nightmares like having seizure. It is better to start treatment for depression under
psychiatrist supervision.
Wish you all the best.
Regards,
