What should I do if my medication caused anxiety?

My neurologist changed my medication (Trileptal) from 300mg in the morning & 300mg at night to 900mg at night only. I only took that new dosage for about 2 days, because I felt extremely high after taking that dosage.

After taking that new dosage, I started to feel very different. Being scared to be home alone, having headaches, lost my appetite, using the bathroom a lot, feeling jittery & just not feeling like myself at all.

My question is, because I stopped taking that new dosage, will I ever feel like my regular self again? I’m still feeling jittery & scared to be home alone. I’m not feeling like myself still.

Should I work out & drink more water? I set an appt. for my doctor this week.

Will I ever feel like my regular self again?
