Unbearable pain

help i got my period when i was 12 or 13 idek. im currently 17, and the cramps only get more n more excruciating as i mature. ive been screaming and crying in bed for like 4 hours now because the pain is so unbearable. the pain killers dont work anymore so i cant stand up and do shit at all. have probably puked in this trash can beside my bed multiple times already. i cant feel my legs either. my mom went in to check on me a couple of times but said that what im experiencing is completely normal? girl im about to see jesus here raaggghhhh
