Speaking as a person who has helped others through the services morass I've tried to steer you to possible places for help. Denver, from his perspective as a person very experienced with dealing with the agencies has also tried to help. Since you laid out a lengthy description of your ills and difficulties you can hardly complain when we try to give what help we can via this long distance medium. I would add the suggestion that you contact heart related support groups in your area. Often those are better able to provide meaningful help than anyone else.

If you say "there is no help for me" then there is no help. There is nothing neither I nor Denver nor anyone else can do for you. Especially when we are communicating via the internet and don't know all the details.

Have you been officially diagnosed by competent medical professionals with CHF? If so did the medical provider recommend any activity restrictions? Most people I know who have official diagnosis of CHF can do whatever they wish as long as they wish. In fact, they are encouraged to go as much as their body will allow. With that in mind the direct answer to your lead in questiion is: Get on the bike and ride.
