I know how you feel, girlfriend! Trust me.
Plus, I'm Miss Paranoia when it comes to lights so I'm immediately trying to figure out what went wrong.

Around here places like Auto Zone will check the light for free and they should be able to pin point problems. It saves time and money. Is there anything like that over there?

Also, ask around for good reputable mechanics. Sometimes the better ones work out of their home garages, because paying rent and employees goes too far. That is how my dad found the mechanic that works on my car and believe me after all thats gone wrong with my car, he knows it like the back of his hand. He is a lot cheaper and gets a discount on parts at places like Auto Zone.

I hope this helps! Stay calm and speak nicely to your car, I am very convinced they have feelings too!
