What if you went mountain biking with a friend or a group of people? Would that ease your anxiety? If its something you truly enjoy doing, and you've been playing sports for the past month with no heart problems, then why not try to see if you can do the mountain biking activity with someone or a group? Have a plan in place in case anything goes wrong.

Can you get weaned off your current psychiatric drugs? Do you really need to be on them? Maybe they are causing these heart problems in the first place and its not a genetic or hereditary cause? Will your medical scans and tests pinpoint what is causing the heart problem?
