I haven't been diagnosed or anything and i'm not a professional at all but I have been reading into the condition and taking assessments and everything seems to be pointing to PTSD. But, the thing is, the PTSD I may have seems to be triggered by the fact that me and my best friend are no longer friends. I get anxious and sometimes panicky thinking about him, I have flashbacks to when it ended, i go out of my way not to be reminded of him, and i cant sleep.

I know online assessments can't diagnose me but it really feels like things are pointing towards some kind of ptsd in me about my friendship breakup. I'm not asking for a diagnosis but is it possible?
