Re: Panic/fears does anyone else feel this way???
I'm sorry about your loss, stressful events like that can definitely worsen anxiety. I hope the Lexapro is able to help you settle back down, keep in mind SSRIs like Lexapro can take a few weeks to start having a noticeable effect.
It sounds like what you are suffering from is anxiety, because you are right panic attacks are sudden and short. Though they do occur together in some of us.
In addition to seeing a psychiatrist Id also recommend a therapist who is familiar with treating anxiety disorders. Cognitive Behavioral Therapy can be very effective at treating anxiety and that way you won't have to rely on the medication alone, though its certainly helpful, especially in tough times.
