Hi darkness. I'm sorry to hear of the stress and poor relationship with your mom. PTSD involves an event of where someone "knows" they are going to die or greatly fears dying or being killed from the situation, or of witnessing such an event.

She does sound controlling, by what you share. Can you find your own voice in these matters? It might be that you need to remind her, "Mom I'm an adult now, and I am doing the best I can. It's all okay and I don't live by your rules any more. Let me find my own rules. Offer to help if you want to, but please don't judge me by your rules any more. " Or something to that effect?

You might want to write down what you decide is the right thing for you to say, and leave it by the phone, or if she comes over alot, put it into your pocket and take it out and read it (or review it) and say it!
