I am scared of how far my dissociation has gotten

So I don’t even remember how long ago this started since I fail to remember anything anymore, but I am genuinely scared. I got into a car crash recently and when I crashed I didn’t care or feel any anxiety, when I do anything reckless I don’t care. I have no urgency or care for anything anymore and that along with memory loss I have no idea what to do to help it. I’m sorry if this isn’t cohesive or well thought out, I just really need help on how to deal with this or lessen the symptoms. And I’ve already tried everything on google, except therapy (which I can’t afford) so if anyone had anything different please help me
