Heart Problem Vs Anxiety

How do I know if I’m having heart problems or anxiety as my symptoms are for both. Chest pain, insomnia, fatigue. I recently did a regular physical annual doctor check up and my blood work is fine. Would something have seen in that if it was a heart problem? I’m so confused. I was told my symptoms seems like anxiety but the chest feeling now is making me freak thinking it’s a heart problem because im not stressed or anxious. Please help. I really don’t want to get overwhelmed or flustered thinking I have a heart problem or possibly spend a bunch of money on doctors looking for a heart problem.
