I don’t have the expertise to try and answer that question but thinking about it logically, if stuff like that could cause tbis then everyone in the world would have suffered many many tbis in their life. Watch kids playing in the park, they are falling all over the place constantly

I think trusting our bodies and telling ourselves we aren’t as weak as think can help a lot. When something bad happens to me like hitting my head or falling on ice, instead of panicking I try and flip the narrative in my head and say, ‘by this happening I’m proving to myself I can take it and that I’m stronger then I thought’. It’s liberating facing your worst fears and realizing they aren’t as scary as you previously thought. Hope that makes sense.
