Is health a barrier to Christian witness? The "get over it" counseling debate

• Is health a barrier to Christian witness?
• Is telling someone to "get over it" appropriate counseling?

A host relays a coworker's theory that poor health — mainly being overweight — saps Christians' confidence and thereby their witness, possibly a way for Satan to interfere. The crew pushes back: one host says anything can be an excuse not to witness, and recounts skipping a church visit because he smelled like smoke. Zach, addressed by name, defends the legitimacy of self-esteem struggles against the 'get over it' response, arguing real issues need real help, not dismissal; others counter that at some point 'get over it' is exactly right, comparing it to grief that must eventually move forward.
