Chest pain that wont cease

I've been having chest pains since early this year. Now, they stopped for about a month, but now they've started again and are continuous. I know they're due to high levels of stress but is there anything I can take to make them stop? Just turned 18 & haven't gone to the doctor in 2 years & I really don't have time to with college

Please be respectful of my situation. Rude comments will be reported. Thank you
