Well, not knowing what meds you are on, I can't comment on their mood altering ability. BUT, what I can and will say is this- you are in pain, not at your house, maybe a little tired, bored, not able to eat comfortably, maybe you haven't even showered...and ALL of that could contribute to your mood....and I don't even want to get into that 'time' off the month...he he he...
