I think that the ground will reappear.....at least you do have the awareness of yourself as being here and you ARE getting things done. Losing time is scary but at least some part of you is functioning and apparently functioning quite well! That is better than me, I am fully present but hardly able to function....I would like to lose time and have some stronger part of myself come out and take over, sort of.....I know that comment doesn't help you. I hope the meditation and the run help you.
I didn't know that about the klonopin causing memory impairment, that is interesting....I am on that now.....
