I'm laughing with you on your "made up health issues" I have many horrible figment issues myself that give me great anxiety. My latest is a random what i think is a blood sugar drop i've been chasing this issue since i sobered up and even the doctors arent sure whats wrong. Tho my doc did say perhaps with my running i'm blowing out my sugar. But it still worries me.
Wish I had more advice to give you on the meds. I refused them myself and I run like you do it helps keep my sanity tho life is not perfect or peachy I doubt if it ever will be. I sometimes get upset that I have to run so much to keep my sanity but I do enjoy it too so whatever works.
