"Suffer with" instead of "suffer from", Using 'suffer' without a specific condition, Mixing up 'suffer' with 'sufferer' as a verb	Confused with 'worry' vs 'care' — 'worry' implies anxiety., Incorrectly use 'worrying' as a noun instead of a verb., Using 'worry' without an object, e.g., 'I worry' should be followed by 'about something.'
Usage notes	Used when expressing emotional or physical suffering; often more intense than simply 'worry' or 'stress'. Appropriate in personal and serious contexts.	Use 'struggle' when discussing challenges or difficulties, both physically and mentally. It's appropriate in most contexts, from casual conversations to more serious discussions about issues.	Used when someone is experiencing pain or hardship. Avoid in casual contexts where lighter terms are appropriate.	Use 'worry' for general concerns. It's neutral but can sound weak in more serious contexts. Avoid in professional settings unless discussing stress.
