Need help. Is 22 too young to have heart disease/congestive heart failure?

It can happen. Unfortunately, sometimes young people also get affected by heart failure. Most often it relates to a viral infection that infects the heart muscle, called "myocarditis". This can lead to substantial heart failure in young patients, and is treated similarly to older patients with hf. However, sometimes the disease can get so bad that heart transplant needs to be considered.
