What am I doing wrong?

I used to be the main person in my friend group of 3. Let’s call my other two friends Maya and Ray. So Ray and I have been friends for 4-5 years. Maya ruined my last friendship, but when it died between them she then came to our group. So then it became 3. Now after about a year of the 3 of us Maya is starting to come between Ray and I. And I have really bad paranoia of her ruining my friendship with Ray. They have been hanging out a lot with out me lately (because I’m on vacation) and I have like mini panic attacks because I’m afraid of being dropped again. I can’t tell if I’m just being a freak or not. What should I do?
