I have binged and purged all day and taken 10 laxatives and a lot of diet pills. Should I seek medical advice, im getting chest pains?

Absolutely! Unfortunately, you are poisoning yourself. You need to seek help to stop yourself from doing this. Call your doctor immediately to assess the damage. Accept all the help you can to get better soon!
Yes. This activity can derange electrolytes cause dehydration and some emetic agents can be cardio toxic . I suspect emergency department next step.
