welcome strawberry

please try not to worry it is not unusual to feel anxiousness the lost of memory may be something to do with the concussion or if your drink was spiked it may have made things worse.( I think people should go to jail for a very long time for spiking drinks for attempted rape or murder ) grrrrrr is the discharge thin & clear and out of just one nostril with a salty sweet taste dose it get worst when you stain or cough if so, and it can be collected your doctor should arrange a beta 2 transferring test or tua test for CSF leakage

Now listen carefully THIS CONDITION IS VERY RARE and it is much more likely to be something else, so the advice is rest rest and more rest, drink a normal intake of fluid and a good diet, we are not doctors I speak form personal experience of a CSF leak but if you have the above symptoms please talk to your doctor

best wishes
