Hi,
IF your brain doesn't produce the right chemicals then I guess you may need help coping with the fear but in the main - every bit of toxin, and all such meds are toxins, have to be filtered out!
Often the cure to get off meds proves more of a problem than the original fear.
There really isn't any cause to be surprise you are worriesd but WILL drug dependency improve that?
With or without drugs you will have to come to terms with the fear sometime - life is like that! That said YOU are the only person who can say if it is right for you. You are 34 so how much damage might the next 40-50 years on drugs do you. Join the rest of us and be frightened but try to learn to cope with it - you have managed so far and you have a supportive young wife, you can do it
Regards,
Greg L-W.
