right to live

Everyday millions of people live with terrible diseases. Terrible enough to make them want to rather end their life than continue living it the way that they are. In my personal opinion life is a privledge, not a right. If everyday people take their own lives because they are capable of doing so, why can some not do so becuase they do not have a capability of doing so? I think that taking ones life is never the answer, but in situations when that may seem the only way out of being locked into hell, they should be able to do so.
