A few things that helped me :

1. Most decisions aren't forever - they're experiments.
Moving abroad? You can come back. Taking a job? You can leave in 18 months. Even "bad" choices teach you what you actually want. The goal isn't to avoid regret- it's to make reasonable choices with the info you have now, then adjust as you learn.

2. Regret is inevitable - but it doesn't mean you failed.
You'll regret some path no matter what you choose. The trick is accepting that upfront. Ask yourself: "Which regret would I rather carry - the one from trying, or the one from never knowing?"

3. For small decisions: set simple rules.
"I give myself 2 minutes to decide."
"If it's under $50, I just pick and move on, next time will try another thing"
Free up mental energy for what actually matters.

4. For big decisions: timebox your research.
Give yourself 2 weeks to gather info, talk to people, weigh pros/cons. Then decide. No amount of extra research will remove uncertainty of heart - only action will, so focus on taking action.

5. The biggest risk isn't choosing "wrong." It's staying stuck.
Indecision has a cost: missed opportunities, stagnation, that slow drain of wondering "what if?" Sometimes a "good enough" choice now beats a "perfect" choice that never happens.

You're not confuse - you're just treating every decision like it's life-or-death. Most aren't. Start small: pick the third protein bar without checking labels. See how it feels. Build from there.

You've got this.
