Separation Anxiety

I think I maybe experiencing separation anxiety from my ex- bf. Or whatever were taking a break right now. When he leaves or I don't hear from him for a while I get nervous and begin to worry. I miss him a lot and get extremely sad.. Sometimes I even cry! His car has been broke down and parked behind his dad's for sometime now and today I was driving past and it was gone and for some reason that like broke my heart. I'm not sure why I fell like this but it's becoming stronger over the past few days
