Vaginismus

I have struggled with using tampons for years. So, i made an appointment at the gyno. When she tried to insert a finger to do a check, she literally couldn’t get her finger in and i was in excruciating pain. She ended up telling me i have vaginismus and i need to get dilators to see if it helps. I’m really new to all this. Does anyone have tips or anything that can help get better?
