I started lexapro about a week ago for depression and 3 days ago i started having intense stomach problems and a huge anxiety attack that took me to the ER.
They said i should stop taking lexapro because of my stomach (they said i might have gastritis, has this caused it to worsen perhaps?) but the thing is after 3 days of quitting lexapro my anxiety is still here. Not as bad, but my heart is still racing 24/7 and i feel like i cant concentrate on anything other then just being calm.

Is this because of the lexapro or possibly the stomach problems thats causing me anxiety?

Before this i had some anxiety once in a while but NEVER this bad. If its because of the lexapro, how long after quitting it will i go back to normal and stop feeling this extreme anxiety?
