I am needed, and I need to stay attached - no matter what happens.

For the body does not consist of one member but of many. 
(1 Corinthians 12:14)

I belong, and I have some tasks to do.

My tasks are specific. Just as the parts of the body have a special purpose, so do I.

These tasks are only accomplished when I remain a part of the Body.
