I have often found myself wondering whether this or that behavior of mine was just my personality or a symptom of CPTSD. But it's both. CPTSD affects everyone differently. It brings out the worst in your natural characteristics. So if you are naturally shy, you might become overly withdrawn. If you are naturally aggressive, you might become controlling.
But then there are things about CPTSD that are so opposite from my personality. I'm not very emotional personality-wise, but then I have these crazy mood swings that I desperately try to reason myself out of.

So I don't blame people when they can't handle being my friend anymore. I have friends with mental disorders that I limit contact with because I can't handle their symptoms for the sake of my own mental health, or simply because their symptoms make them not fun to be with. It sucks. But I get it.
