I have had these problems
for 20 some years due to brain damage and
keppra has not made it worse or changed anything
for me though. I am on a high dose and on other seizure meds. You may want to see about a mood stabilizer for her I know she is young it may or may not work. If it is the med maybe switch meds no one needs to feel that way and I know from experience it's not fun not being yourself and putting others through it.
