HELP!! I can't get my menstrual cup to open

I am a 17 year old, active tampon user and i recently bought a 25ml menstrual cup.

I have been practicing some dry runs before my period but ran into some problems.

I can get the cup in without a hitch but
after it's in it will not pop open and instead just collapse in on itself.

I have tried the labia fold, punch down fold, and ⁷/triangle fold and none of these pop open.

I have tried every trick that i have read, relaxing my vagina, pushing it in and out, squeezing it, twisting it even tried to get it to manually open! None of these worked.

I really want my menstrual cup to work out and at this point i just don't know what to do. I feel like I've lost hope in ever getting it to work.

Should i downsize?
