I'm so happy to see you back here on the cardio forum once again - I've been worried about you and it would seem rightly so. Not that I'm one to talk re stress and all, but I recently went through a severe depression as well. I went from Lexapro to Zoloft 100 mg. I am sorry to hear that you've been feeling so badly and I hope you keep posting here! You realize that many people with heart disease suffer with depression and sometimes it goes along with heart disease.
You are not a failure! This is a pitfall in your life and you will go on from here. I know all this happening isn't helping your mind set, but don't give up! I'm here for you, along with many others!
Take care of you that's number one!! Hugs and Love, Teri
