I had 5 bypasses last year and a defibrillator installed 6 months later. Never had an issue with depression until then. Anxiety yes, the year building up to the surgery was very bad. I was on medication for anxiety to get that under control. Now I deal with depression and "pump head" which is a change in personality. I was very patient and understanding but now I have no patience and get angry for no reason. It sucks, we all deal and if anyone needs to talk I feel that is why we are here. Someone is usually online.
