Hi and Welcome to HealingWell, love!
While I don't know your prior history to having all these valve problems, but I do know that many of the symptoms that you are having can be attributed to heart valve problems. I'm sorry to hear that you are having all these troubles!!
A good site to learn more is;

I have mitral valve regurgitation and stenosis, but so far I've been lucky enough not to have any noticeable symptoms as yet. Have you discussed any of your questions with your Dr.? - that would be my main suggestion...
Are there any support groups in the area that you live? - a local American Heart Association group?
Please take care!
Hugs, Teri
