i started lexapro about a month ago. i was starting to feel better. about two weeks ago i caught a nasty cold. didn't go away, ended up turning into a sinus infection. i am now extremely dizzy. i am convinced i am dying, or something is wrong with my head. i am also on an antibiotic called bactrim which makes me sick to my stomach, which i also think it contributes to the dizziness.im just so depressed that a sickness can rule my life. when i was younger, i am only 21 though, i would get sick get better and think nothing of it. now i dwell on it all day, and it consumes my mind. how long should it take for a sinus infection to disappear? i have only been on the antibiotics for 2 days and need to take them for 7. does anyone else think like this, or am i crazy?

No you are not crazy. Try and stay calm and your infection should end soon, if not see the doc.
