Hello
@spuntfaround - my suggestion is you seek out the services of a good psychiatrist and let him know about your phobic aversion to bugs, roaches and loss of control.
You may have more than cptsd going on at the moment. You need to seek professional help to find out and potentially obtain appropriate treatment.
Losing control of yourself, breaking things, throwing things, saying things that you don't remember is not, on its own and in my opinion, attributable to cptsd. But I'm not a health professional and that's the only type of person who can really determine what might be causing this.
I don't know if you're blacking out. Sometimes rage attacks can be like losing a sense of reality but then so can lots of other mental and emotional episodes.
Whilst you are obtaining your referral to get to the psychiatrist - if possible - also ask your gp to run some blood tests to eliminate any physical causes too.
Good luck
