Was this a panic attack or something else?

I have panic attacks, and this very well could have been a very severe one. However, there are a few things (nerve issues, severity of disorientation issues, etc.) that make me think this could be more serious. Are you still having issues with your fingers? Those sound like nerve damage or something, either from the weight accident or something else. You should see a good neurologist and regular doctor to rule out anything else. If these are panic attacks, they are exceptionally bad ones. You mentioned that you take drugs recreationally. Any sort of drug whatsoever that someone who has intense anxiety takes is magnified. There are things I've done that have changed me in a way that I can't undo.
