Hi @Chris
You sound like you are really understanding where all of those 'feelings' are come from. The want to run away and avoid everything, for me when i want to run away its usally because i want to avoid the pain... I think for me though i've had to learn to kind of stand still with those feelings, like there is a snake close by to me and instead of running its better to stay still and wait for it to move on.
I also often think that other people are thinking negative things, and work myself up to the point that i'm SURE, im Positive/certain that someone is angry with me/hates me/annoyed with me... but the few times i've actually been able to suss things out its not acutally been the case or to a far lesser degree than i had imagined (mostly stuff with my psychologist lol - would never be brave enough to ask someone in 'real life').
Hold on, you are in the middle of something really tough, but you never know what might come out of the other side, its ok to feel like running, and for those things to be triggering, by sticking it out you might be able to lessen them somewhat and challenge them inside yourself.
Good luck,
