We all get  block in our heads sometimes. Maybe you replay one small mistake from three days ago, or maybe your heartbeat fast for no reason when the room is completely quiet. You know something feels off, but is it overthinking, or is it anxiety?

Most people use the same word, but the truth is that Overthinking vs Anxiety are two different things. The difference might be subtle, but it finds what kind of help actually works for you.

Signs You’re Overthinking 

Overthinking vs Anxiety is a mental loop. You live in the “what if” world. You think too much, reflect, and replay.

• Difficulty making decisions
• Thinking about a small problem until it becomes a huge one
• Assume people’s words, tone, or facial expressions
• Overplanning for situations that are not even real 

Overthinking feels like your brain is too noisy, but your body stays still.

Why you overthink

A lot of overthinking comes from:

• Low self-love
• High standard
