welcome
people who have panic attacks dont crash their cars and in general should keep driving
if the lexapro side effects are too much of a nuscience you can cut the tablet and take half a day for a while, when and if it works, it will help a lot
CBT info is in many self help recovery books for panic disorder and agoraphobia, on line bookshops have these, some can get all the info they need from the recovery books, others need to see a therapist of some sort for their CBT instructions
try to get some valium type meds, these go well with lexapro and always help to reduce the anxiety
a valium tablet disolved under the tongue will greatly reduce any panic attack but sadly many docs are completely against them and wont prescribe any
