I Think I Have Neurological/heart Problem

Hi im 18 and I have had an attack recently. It feels like someone is squeezing my heart and i go into a massive sweat chest feels weird i can barely walk vision is all blurry. And i immediatley start slurring my words, and my head feels like it gets really tight. And lately I have been having trouble with my words I get them mixed up have hard time saying them. And sometimes when I talk a few of my words end up coming out as gibberish. This has happened 2 other times before my most recent one. Ever since the most recent I havent felt myself at all. Should I be concerned?
