How do I know if I have CPTSD vs PTSD?

the difference is PTSD is caused by a single traumatic event like a car accident, while C-PTSD is caused by a series of traumatic events like domestic violence or child abuse. PTSD triggers are usually more specific and directly related to the event, like being afraid of driving after an accident. C-PTSD triggers tend to be more vague and harder to link to one single event, like being terrified when someone raises their voice or even just someone speaking with a specific speech pattern. A "complex" medical condition usually just means there's more than one obvious symptom, i.e. simple vs complex cysts or migraines

I didn’t think I had CPTSD either but most of mine didn’t come from family, it was from friends and events in my younger years. I would just keep moving fluidly with the process and look for the (I hate this term) the “little t” traumas which may have meant more to your younger self which you brush off as “silly “ or “overreacting” to your grown up self.
