I suffer from depression but it has been well controled for years-taking welbutrin. I am 7 weeks post op and for about a week now I can not "shake" the depression. I am not depressed about pain (it is now minimal), or circumstances-just depressed for no real reason. I read online that major surgery can cause depression-does anyone else know about this? Is it from the anesthesia? I was under for 11 hours total-9 for the surgery and it took me 2 hours after surgery before I was awake enough to breathe on my own. Maybe from that?? I would call my primary to get some dif meds but I just swithed docs and my appt is not until nov.
