Hi BoogsB,
Welcome to pc central - I am sorry that you have had so many traumatic things happen to you - I hope things are better for you now
yes any one of those incidents could have triggered PTSD.
Do you have a safe place to live now? I hope so - can you get access to therapy? a trained professional could help you work through all of this and help you moe forward
take care P7
