I went to a family practice nurse for bad anxiety and panic attacks.  She prescribed .25 Zoloft for a week before upping to .50, and .5 Ativan to use as needed for panic attacks.  Having never taken either before and terrified of the possible side effects, would it be ok to split the doses in half and start from there?  I have awful health anxiety and any new symptoms or side effects from the meds would scare me so horribly.
