Hi there ,
Welcome to Just answer !
Well, if you have been diagnosed with TLE , then i must tell you that this type of epilepsy has got its own psychiatric manifestations which include anxiety and depression , so TLE could very well be the cause of your depression and anxiety..so it will be a good option to seek help of a neurologist in this regard and take his opinion . but i would like you to continue on the drug regime , ofcourse the revised regime as we have discussed earlier..
Secondly , valerian is a herbal medicine , which is effective for inducing sleep in those who have insomnia , however , nowadays increasingly researchers are endorsing it as a product which can help in depression , anxiety , stress as well..
Since it is a herb and the side effects are almost nil , so there is only positive to take from this medicine , so i will suggest that you give valerian a try , atleast it will help with your sleep , if nothing else..
I hope this helps..
Wish you all the best..
