To those who replied so quickly, and those who may read & respond in days ahead: Thank you for all of the wisdom & encouragement!
I was feeling quite negative about my experience, but now I can see there may be light at the end of the tunnel. It makes sense that there would be adjustment time--for me & for my heart! I think what really bothered me the most was the fact that I had already fought through afib symptoms (with help--a long road of cardioversion, then ablation & different meds) & had been feeling more energetic overall than I had in a long time, in spite of what I called my "bad days" . In the week since the procedure, I seemed to have fallen back into fatigue, shortness-of-breath, and every day was seemng like a bad day. The positive comments have made me feel that, having battled through before, I can do it again. For one thing, I am back to walking every day & that feels good. It will take time and some adjustments here & there, but I am hopeful for a good outcome.
Having said that, I still feel that there is room for improvement in the overall process: 1-More education!! There should be a class/instructional video before or immediately after the procedure to explain in detail what to expect, how the device functions, how you may feel. 2-More tech support! I can barely use a cell phone as it is, plus I was given wrong info as far as using the app. I know the device is not dependant on the monitoring system to function, but monitoring would be a way for my doctor to know how well it is functioning, which would be reassuring. I feel that no one should leave the hospital without a system that they understand & that has been proven to work properly. 3-Everyone should be made aware of support sites like this! Just in the day or so since posting here, I have felt better mentally & physically. That may actually be the most important thing! Anyway, thanks again, everyone!
