Can 26 year olds have heart attacks or does something else cause similar issues?

Being as I understand the symptoms for heart attacks I continue to worry. I'm male 26 years which means i have a better chance to win the lotto. I used to drink caffeine a lot and smoke but have almost wiped the habits out. A while back someone slipped something in a drink and the results was an anxiety attack with chest pains and all that lasted almost 20 hours I went to the hospital and they said my heart was fine EKG what not just learn to breath right. That was three months ago but lately my chest has been hurting and the pain ranges from like plain old body ache feeling like you've don't to much Weight lifting to a warm numbness and all the way to a stabbing feeling that spreads out into my right lung areas like pin pricks. Its like someone has a hand around my heart and is squeezing it making it hard to breath. I went to the doctor again she said it was anxiety and gave me Med.s for it... they do nothing but make me tired. The problems I been having have been getting Better then worse stc. The other (WED) day i was just hanging out bowling and all of a sudden i got dizzy and when i check my pulse it was upwards of 90. Tonight (SAT) three days later about 2 AM I awoke up not breathing gasping for air and dizzy and my heart was practically beating out of my chest but faded and quickly my whole chest went numb ya no more ache but then i got dizzy again and my heart started beating out of my chest in hyper-mode. I checked my blood pressure to be 165 h 109 d 93 beats. which is the highest ive ever seen period. A shooting pain then numb then pain for about thirty minutes then I got really tired and went to lay back down. Something popped in my chest and now i'm fine. Chest still aches right down the middle but my heart levelling down to about 80 beats 135h105d I hate for it to be the weirdest case of heartburn ever but its getting worse every night and when i try to get up in the morning I've been weaker and weaker to the point that I can't get out of bed. Even walking is getting hard to do without effort and hard breathing. The only history of heart problems my family has is murmurs on my sister and mom but my mom has something she called hernia of her stomach that she says caused her the same problems when she was younger. I doubt it. Need help can't afford an emergency room visit again last time it cost over a thousand dollars and i only have like maybe 400. Ive been through the ringer with many images taken of my neck and upper chest because all the limp nodes are slightly swollen two years now but i don't think that would be related to anything else.
