Do i have fear of abandonment?

I am so sorry to hear about this, but it is pretty common. I am not sure if you have any previous diagnoses, but it could most certainly be PTSD or Generalized Anxiety Disorder. Both of these are extremely treatable through things as simple as talk therapy or EMDR (a trauma treatment). More info is available online, but the first step is to contact your primary doctor or a therapist. I hope this helps :D
