Hi Pam,
sorry for your loss. It’s only natural for us to fear death. Our body and mind constantly reminds us that things are different, and life can be short. i have such a hard time talking to others about death because they get so uncomfortable.
Let me just say, i can tell you have very healthy coping skills and not everyone is that lucky. you actually did something healthy for your body, heart, and mind by walking. I have not had a recent loss but i constantly think "at least now i know I’m going to die from a stroke" even though many other things can happen to me. for me these distorted thoughts are about fear of the unknown, shame of being weak, and much more i haven’t realized yet. i think our first step will be recognizing or labeling our emotions and cooping in healthy ways. We will get there one day at a time. keep your head up and thanks for sharing.
