Hey all. Thanks again for the replies. I've myself wondered if this was merely PTSD alone, or something else on top of PTSD. She definitely does have the symptoms of PTSD like the flashbacks and nightmares etc. But I worry there's more to it also. As I said, BPD has crossed my mind, as well as potential paranoid schizophrenia. Because she has said that sometimes she is delusional and hallucinates. Sometimes she says she gets afraid of me, which is extremely upsetting because I would never harm her. She knows this when she's calm and in the here and now. But sometimes out of the blue, she will threaten to block my number and get a restraining order when I text her. I'm like whoa!! Then she admits later that at the time, she felt threatened by me for some reason and it wasn't my fault at all. But I've never threatened her or harmed her before in my life!
She claims it is all PTSD related. That her paranoia is due to flashing back to when she has been harassed and stalked in the past. She says that's why she panics like that.
One time, in particular, I was at her apartment and she just randomly woke up one day and was extremely distant. I asked if she was okay and all of a sudden she just said, so calmly, that she couldn't be with me anymore and wanted to break up. Just the night before, we were cuddled up watching movies. I was horrified and in shock - even though this behavior is somewhat common, sadly. I tried to talk to her to understand, and the more I tried to talk, the more she began panicking. she was yelling at me to leave over and over and threatened to call the cops. She looked genuinely in a panic. I swear, if I hadn't just left, she would probably have actually called. I was horrified. She explained later that in that moment, she felt like she was reliving moments from her past where she was in danger and couldn't distinguish reality at that point.
I guess I'm just wondering if this is all merely PTSD symptoms, or if some of these could reach into schizophrenia? I've read that delusions and hallucinations can exist within some serious cases of PTSD. And her description of what's going on in her mind at that moment, as far as flashbacks and reliving certain events, does fit the mold for PTSD.
It just shocks me how she can go from the most sweet, kind, and loving girlfriend to this cold, almost frightening person who wants me out of her apartment and out of her life in literally the blink of an eye. It's actually really horrifying. and it leaves me distraught and confused as hell as to what the heck just happened. I wind up feeling like I'm going crazy.
She feels legitimately like two different people sometimes. And it happens so fast. This cold, angry person and this sweet, loving one flip flop so darn quick. I've even wondered if she has dissociative identity disorder, it can be so extreme, except she doesn't have the symptoms of amnesia etc.
Anyway, I'm ranting at this point. Thanks again for the replies. They're all very helpful.
