What to do

Going through something that’s been mentally challenging for me. Today I just freaked. I lost my vision, my arms, hands and feet went numb. My chest was tight, my throat felt like it was closing and I was gasping for air so hard I think I might’ve blacked out for a minute. I could hear my partner telling me to breathe but it sounded like he was so far away, when he was right next to me. It took me so so long to finally calm down. I need help 😪😰
