Sabrina,
You say you were out earlier in the day shopping so if the heart attack had happened then far more people would have known, so how much of an issue would that have been ? If it wasn't a major problem then the choice to return to dressing out is an easy one , just do it and enjoy it as before. I'm 4 years older and the issue doesn't really concern me most people know about my dressing , the family may not be happy but now I've separated they will just have to accept it's part of me .

I suggest you don't purge but work on your health and fitness level , you may never have another attack and regret the hesitancy for the rest of your life . I accept the window is only open for so long make the most of what you have .
