Hi I Am Currently On 1200mg Of Carbamezapine For My

Hi I am currently on 1200mg of Carbamezapine for my epilepsy and 10mg of Citalapram. Yesterday, I went to the dentist for some prep work for a crown. I have a high gag reflex and the taking of the impression of my upper and lower teeth was a horrible ordeal. Anyway, I came out of the dentist and just sat in my car and cried. I had really bad mood swings all day and just wanted to pick holes in everything anyone said to me (which isn't normally like me). Even in the afternoon I had a massive crying session. I just didn't feel right in my head. Was this an effect of the dental anaesthetic with my carbamezapine or the Citalapram?
