New Here, had ablation and pacemaker (scared now)

Hi all, I am a 47 year old female that has been in pretty good health until about 6 months ago when I went to my pcp with severe shortness of breath.  He did an ekg and said I had atrial fibulation as well as high blood pressure and a slow heart rate.  He put me on diovan for the blood pressure and blood thinner for the a fib then referred me to an EP doctor after doing an echocardiagram and a nuclear stress test which both of those came out okay.  The EP doctor told me that I had atrial flutter instead of afib and felt confident that he could fix it by ablation.  I went to the hospital 1-09-06 for this and he felt like it was a success but immediately after this procedure he told me that I really should have a pacemaker because of my slow heart rate.  I agreed to have this done as well and had it put in the next day.   Well, since then I have had good days and bad days.  I was off work for 2 weeks and have been back at work now for 2 weeks.  I am starting to have my shortness of breath again especially in the late afternoon and early evening.  I worry if what I had done was a success or perhaps I am expecting too much too soon.  Needless to say I am frustrated and also scared for what my future holds.  I would appreciate any comments and/or encouragement from fellow members regarding ablations and what to expect as far as recovery goes.
