Hi SorryShaped,
I am very concerned about you.
Forgive me, as I am a little unclear myself. Do you have a feasible way to go home or to a doctor or to the ER, if needed?
You have a lot going on. The house is one of your current triggers. It might help you if get out of that setting. (?) I don't mean for you to abandon your parents; yet, I do think you will need to come to terms with the fact that you alone, will try to help, but most likely would need additional assistance.
It surely does sound like your parents are having an incredibly hard time. I do know how sensitive you are, and have been, to your parents' needs. It seems like they need a lot of help, pronto.
We, often, are not able to give them all of the care they often need.
I am feeling (In reacting to your description), like you need help sooner rather than later?
Do you have a friend who is willing to take you to your car, to your apartment, anywhere you might need to gro?
Have you used a hotline that has been helpful?
Are you feeling any safer than when you had started this thread?
The immediate goal for you, I'd think, is getting yourself squared away. You cannot help others if you do not help yourself.
You have a few obvious needs at this point. You need to be safe. You need to minimize the PTSD, which you feel is being set off by being in their home. You need any suicidal ideation to stop, etc.
Would they be okay if you were not with them tonight?
Would they be okay if you were not with them for 24-48 hours?
How do you get into a safer environment tonight or ASAP?
What helps?
