Spaced and confused

Went to the doc this morning and had a little chat and procured some meds. It's strange that I thought these things made me feel better as although my heart is no longer pounding in my chest, I feel spaced, lethargic and 'down'. I wasn't expecting this at all, maybe my expectations were too high (pun intended!), perhaps I was seeking a miracle cure to which there is none. I guess I have to give them time to kick in but I've only had half a tablet today and am now feeling quite sceptical as to their benefits. Still I'll see how I feel tomorrow. Maybe I shouldn't have gone back on them at all (the doctor didn't necessarily think I should, which surprised me!) and now I'm wondering if he was right. Well too late now I guess.
