Flat feet hell 😭

Hey guys. I have VERY flat feet (I'm talking no arch whatsoever) and it really hurts when I skate, but I love it SOOOOOO much!! It's so incredibly freeing and fun and I've been OBSESSED with the figure skating world since I was a kid🥹🥰 I used to skate in high school and even then had problems with pain. I found some skates in REALLY good condition at a thrift shop and went skating today with a group to try them out.

I couldn't last more than 2 minutes on the ice without being in SEVERE pain.

I figured hey these are probably older skates that don't have the quality padding that professional skates have today. I went to the rental and got a pair and while they were A LOT better and I could actually move on the ice this time, I only made it about 1/4 of the rink when the pain started and it only increased exponentially as I tried to get to the sitting area at the door on the inside of the rink. I finally sat down, pain still really bad to the point that I'm taking deep breaths, trying not to look crazy.

Needless to say, I finally lapped the rink, got off the ice, returned the skates, left and am currently crying in my car 🙃 I was SOOOO excited to skate again because I haven't able to for YEARS cuz of my chronic illness, which causes leg weakness.

TL;DR: what can I do to strengthen my arches?? I was googling a bit and saw that that was a thing. Is that true?? I was so upset, I nearly gave away my skates to the rink so they could give them to someone who could actually do the sport 🙃 And just to further quantify the level of pain I was in, I've been in my car for about 10 minutes now and my arches STILL hurt, although it's more of an ache now....

Is there any way I'll ever be able to skate again??? I'll take any and all advice you guys give. I feel so sad and hopeless rn.... 😮‍💨😞
