all antidepressants can make you feel worse at first and if you are already in pain or have discomfort, I would wait to feel better
lots of info about depersonalisation on the net, can be confused with lightheadedness, a separate problem
anxiety sufferers are unusually sensitive to early antidepressant side effects and I would start at half a 15mg tablet of remeron and work up to 3o or more
valium also helps, either on its own as needed, also to get uesd to the remeron
