My Dr. prescribed drugs for bronchitis and now I feel like I am on a bad trip, depressed, horrible, scared:?

I am on prednisone, albuterol, augmentin, and I take Wellbutrin. Out of nowhere I feel suicidally depressed and high, except not a good high. This is awful. I feel disconnected from the rest of the world and extremely sad... beyond sad. Does anyone have an idea as to what drug interactions may have caused this? I just looked in the mirror and my eyes are totally dilated. Like I said, I feel extremely scared and extremely depressed.
