PTSD Triggered

I have been majorly triggered with my PTSD which I have from the pregnancy ad birth of Angel. I'm sitting forcing myself to write this because what I really want to do is dissociate and shut off to not have to deal with it. Unfortunately the trigger is still active and it won't be going any time soon.

When I was pregnant and enduring the nausea 24/7, the chip shop next door opened up and the smell was very nauseating and made me feel much worse. Thankfully it was winter and having the windows and doors shut helped, I just had to avoid going out when the smell was there; everyday from half ten in the morning until half ten at night, except Sundays when thankfully they didn't open. Getting to the car to go out was like getting through a mine field of smell and it made me feel so bad that usually I would end up back in the house feeling ill and panicky. The nausea stopped being 24/7 but it was still there through the summer months even, before I had her and the smell got worse with the heat. So today with all the windows and doors open and that same smell wafting in and filling up the house, its finally won and I've turned into a wreck and I can't deal with it any more. I feel like I'm going to pass out and I'm fighting to keep my dinner where it should be which is triggering me more. I feel like I'm trapped but I'm in my own home. I can't not have the windows open and the only fan we have is in Angel's room and would only help waft the smell around more anyway.

I have lit a load of scented candles and closed the window as much as the weather will allow but I still can't stop smelling it and I can taste it too, like that greasiness is inside me.

The day I gave birth to Angel smelled the exact same and was hot although very wet. Right now I don't think it would be a good idea to go into the birth story, I know I probably would pass out or just dissociate for the night. The best thing I can do is to try to focus on anything else, keep cool and treat the effects of the panic as they come.
