Idk what to title this

For backstory I have really strong fear of abandonment, it even gives me panic attacks and the smallest things can trigger the worst ones. Back in February I was super excited to go to the winter semi-formal at school and my only method of transportation was my boyfriend because we both live 30 minutes away in the same direction, all of my friends at least 20 the opposite way. And my parents loathe driving me anywhere (can’t even take driving lessons because they’d have to drive me there). Something came up, said he was sick and I know he doesn’t like dances so I just bit the bullet. Today I found my school’s social medias and found a picture of my boyfriend at the dance he couldn’t go to with his friends, happier than he’s ever been at a dance with me. I spiraled into a panic attack and it keeps coming back. No matter what I do. I confronted him and he wants me to tell him how to fix it but I can’t even think about doing something with him without spiraling again because all I can think is that hed be happier with his friends, he doesn’t care enough to come up with something. I’m supposed to fix it. I’m supposed to be okay. I’m supposed to make him happiest. I’m supposed to be important.
