You'll have to wait for the results of the AE panel. There is nothing that can be done about that....even in this country things like certain cultures can take weeks to grow and answers given. Try to be as patient as possible.
Does anything soothe you? If it's the 5-HTP, then the effects may wear off. The doctors sound as if they're doing all of the right things, I can't think of anything else. Can you walk for short periods of time, focus on anything at all (and by the way, it's not uncommon even after surgery to have problems with that), looking at a magazine filled with more pictures. It does take time for the brain to settle down again.
Would you be any better in your bed at home? I doubt it even though most of us are glad to be released from the hospital. But for now, I'd say you're exactly where you need to be. Feel safe there because you are. Yours, Lenora.
