First of all, you have to interpret what your definition of suffering in silence is. Meaning it could either be physical- or psychological pain. Either way, you should get help.
Though there are many who look upon this as being brave, myself included. The reason so many think of this as doing something honorable is because we perform something we don’t really dare to do, which is the very definition of being brave.
My conclusion is that it may be brave to suffer alone, but if able, get help!
