Just woke up vomiting, choking on vomit, not drunk or on drugs, heart beating slightly off. Is this ER worthy?

I am in the US, so financial calculations need to be factored in.

For a moment, I couldn't breathe, felt like I was going to die, then vomitted.

Now heart beating slightly off, not feeling great but not terrible, had mild chest pain earlier in evening...

Kinda feel off. Have medical insurance with large deductible.

Ignore it? Taxi to ER? Call 911? Genuinely don't know and don't like 911 since police are involved.

Also I feel hot, feel burning around my neck.
