Are Panic Attacks And Nocturnal Seizure Related To Epilepsy?

Question: I had first full epilliptic attack in 1988 when I was 11 years.I became unconscious and froth came out of my mouth.I was diagnosed as having PCS with or without secondary generalization.I was given various sort of medication.I never became unconscious again.All my MRIs,CT scans and EEGs came normal.In 2004 I went to Apollo Chennai where they gave me lamitor and it was tappered off and medicine was stopped in 2007. In 2004 my mother was diagnosed with heart problem.I started worrying about her.In 2005,my heart rate was around 110-120.I went to Apolloo where they tested me with Echocardiogram.After the test they advised me from taking mental stress. In February 2006,I had my first panic attack.In July 2006,I had my second panic attack.I saw a psycologist.He put me on Paroxetine 25 mg.But it did not help.I myself started controlling the attack using meditation,ayurvedic medicine. In October 2008,I was travelling from Guwahati to Silchar.At night I fell from my seat and was unconscious for 15 minutes.Next day I had a CT scan done.Everything came out normal.Again in February 2010,I became unconscious while sleeping.I had bit my tongue .Again all my CT scan and EEG report came normal.But I was diagonized as having Nocturnal seizure.I am put on Sodium Valporate CR-300 mg twice daily. Till date,I have not yet suffered any more Nocturnal seizure,though I am not completely sure about it.At present I think that I can again get this epillipesy.That is why I sometimes get anxiety attack . I can control these attack.I am afraid of diseases.I found out that thought of having epilepsy is acting as trigger of my panic attacks.I have become a hypochondriac.When I am having this anxiety attacks I get a feel of grief,panic,tense.I feel that something bad will happen to me.To control this,I start counting numbers,sometimes pinch myself and attack slowly subsides. I never had a day time full seizure since 1988. I have a constant fear that my epilepsy will again relapse and it will ruin my career. My question is 1)Whether these attacks are related to epilepsy? 2)What is the prognosis of my disease? 3)Sometimes I feel sleepy whole day.Is it due to effects of medicine or something else?

Why I am getting Panic/anxiety attacks?Is it some sort of Partial seizure.?I am at present taking 300mg Sodium valporate CR twice daily.Is it the right dose?How will I know if I am at present getting nocturnal seizures?Will there be any adverse effect if I take Sodium Valporate over a long period of time.Last year ,I checked my SGPT/SGOT level.It was normal.Is this nocturnal seizure related to my childhood epilepsy?

Since I am taking sodium valporate 300 mg CR twice daily since Feb 2010,what should I do know?Shall the dose be increased or be tapered down.?
